7.  Discussion:

The Bluebook report material indicates that other radar unknowns were being observed at Lakenheath until about 0330Z. Since the first radar unknowns appeared near Bentwaters at about 2130Z on 8/13/56, while the Lakenheath events terminated near 0330Z on 8/14/56, the total duration of this UFO episode was about six hours. The case includes an impressive number of scientifically provocative features:

  1) At least three separate instances occurred in which one ground-radar unit, GCA Bentwaters, tracked some unidentified target for a number of tens of miles across its scope at speeds in excess of Mach 3.  Since even today, 12 years later, no nation has disclosed military aircraft capable of flight at such speeds (we may exclude the X-15), and since that speed is much too low to fit any meteoric hypothesis, this first feature (entirely omitted from discussion in the Condon Report) is quite puzzling. However, Air Force UFO files and other sources contain many such instances of nearly hypersonic speeds of radar-tracked UFOs.
  2) In one instance, about a dozen low-speed (order of 100 mph) targets moved in loose formation led by three closely-spaced targets, the assemblage yielding consistent returns over a path of about 50 miles, after which they merged into a single large target, remained motionless for some 10-15 minutes, and then moved off-scope. Under the reported wind conditions, not even a highly contrived meteorological explanation invoking anomalous propagation and inversion layer waves would account for this sequence observed at Bentwaters. The Condon Report omits all discussion of items 1) and 2), for reasons that I find difficult to understand.
  3) One of the fast-track radar sightings at Bentwaters, at 2255Z, coincided with visual observations of some very-high-speed luminous source seen by both a tower operator on the ground and by a pilot aloft who saw the light moving in a blur below his aircraft at 4000 ft altitude. The radar-derived speed “as given as 2000-4000 mph. Again, meteors won’t fit such speeds and altitudes, and we may exclude aircraft for several evident reasons, including absence of any thundering sonic boom that would surely have been reported if any near hypothetical secret 1956-vintage hypersonic device were flying over Bentwaters at less than 4000 ft that night.
  4) Several ground observers at Lakenheath saw luminous objects exhibiting non-ballistic motions, including dead stops and sharp course reversals.
  5) In one instance, two luminous white objects merged into a single object, as seen from the ground at Lakenheath. This wholly unmeteoric and unaeronautical phenomenon is actually a not-uncommon feature of UFO reports during the last two decades. For example, radar-tracked merging of two targets that veered together sharply before Joining up was reported over Kincheloe AFB, Michigan, in a UFO report that also appears in the Condon Report (p. 164), quite unreasonably attributed therein to “anomalous propagation.”
  6) Two separate ground radars at Lakenheath, having rather different radar parameters, were concurrently observing movements of one or more unknown targets over an extended period of time. Seemingly stationary hovering modes were repeatedly observed, and this despite use of MTI. Seemingly “instantaneous” accelerations from rest to speeds of order of Mach 1 were repeatedly observed. Such motions cannot readily be explained in terms of any known aircraft flying then or now, and also fail to fit known electronic or propagation anomalies. The Bluebook report gives the impression (somewhat ambiguously, however) that some of these two-radar observations were coincident with ground-visual observations.
  7) In at least one instance, the Bluebook report makes clear that an unidentified luminous target was seen visually from the air by the pilot of an interceptor while getting simultaneous radar returns from the unknown with his nose radar concurrent with ground-radar detection of the same unknown. This is scientifically highly significant, for it entails three separate detection-channels all recording the unknown object.
  8) In at least one instance, there was simultaneous radar disappearance and visual disappearance of the UFO. This is akin to similar events in other known UFO cases, yet is not easily explained in terms of conventional phenomena.
  9) Attempts of the interceptor to close on one target seen both on ground radar and on the interceptor’s nose radar, led to a puzzling rapid interchange of roles as the unknown object moved into tail-position behind the interceptor. While under continuing radar observation from the ground, with both aircraft and unidentified object clearly displayed on the Lakenheath ground radars, the pilot of the interceptor tried unsuccessfully to break the tail chase over a time of some minutes. No ghost-return or multiple-scatter hypothesis can explain such an event.

I believe that the cited sequence of extremely baffling events, involving so many observers and so many distinct observing channels, and exhibiting such unconventional features, should have led to the most intensive Air Force inquiries. But I would have to say precisely the same about dozens of other inexplicable Air Force-related UFO incidents reported to Bluebook since 1947. What the above illustrative case shows all too well is that highly unusual events have been occurring under circumstances where any organization with even passing scientific curiosity should have responded vigorously, yet the Air Force UFO program has repeatedly exhibited just as little response as I have noted in the above 1956 Lakenheath incident. The Air Force UFO program, contrary to the impression held by most scientists here and abroad, has been an exceedingly superficial and generally quite incompetent program. Repeated suggestions from Air Force press offices, to the effect that “the best scientific talents available to the U.S. Air Force” have been brought to bear on the UFO question are so far from the truth as to be almost laughable, yet those suggestions have served to mislead the scientific community, here and abroad, into thinking that careful investigations were yielding solid conclusions to the effect that the UFO problem was a nonsense problem. The Air Force has given us all the impression that its UFO reports involved only misidentified phenomena of conventional sorts. That, I submit, is far from correct, and the Air Force has not responsibly discharged its obligations to the public in conveying so gross a misimpression for twenty years. I charge incompetence, not conspiracy, let me stress.

The Condon Report, although disposed to suspicion that perhaps some sort of anomalous radar propagation might be involved (I record here my objection that the Condon Report exhibits repeated instances of misunderstanding of the limits of anomalous propagation effects), does concede that Lakenheath is an unexplained case. Indeed, the Report ends its discussion with the quite curious admission that, in the Lakenheath episode, “…the probability that at least one genuine UFO was involved appears to be fairly high.”

One could easily become enmeshed in a semantic dispute over the meaning of the phrase, “one genuine UFO”, so I shall simply assert that my own position is that the Lakenheath case exemplifies a disturbingly large group of UFO reports in which the apparent degree of scientific inexplicability is so great that, instead of being ignored and laughed at, those cases should all along since 1947 have been drawing the attention of a large body of the world’s best scientists. Had the latter occurred, we might now have some answers, some clues to the real nature of the UFO phenomena. But 22 years of inadequate UFO investigations have kept this stunning scientific problem out of sight and under a very broad rug called Project Bluebook, whose final termination on December 18, 1969 ought to mark the end of an era and the start of a new one relative to the UFO problem.

More specifically, with cases like Lakenheath and the 1957 RB-47 case and many others equally puzzling that are to be found within the Condon Report, I contest Condon’s principal conclusion “that further extensive study of UFOs probably cannot be justified in the expectation that science will be advanced thereby.” And I contest the endorsement of such a conclusion by a panel of the National Academy of Sciences, an endorsement that appears to be based upon essentially zero independent scientific cross-checking of case material in the Report. Finally, I question the judgment of those Air Force scientific offices and agencies that have accepted so weak a report. The Lakenheath case is just one example of the basis upon which I rest those objections. I am prepared to discuss many more examples.

8. The Extraterrestrial Hypothesis:

In this Lakenheath UFO episode, we have evidence of some phenomena defying ready explanation in terms of present-day science and technology, some phenomena that include enough suggestion of intelligent control (tail-chase incident here), or some broadly cybernetic equivalent thereof, that it is difficult for me to see any reasonable alternative to the hypothesis that something in the nature of extraterrestrial devices engaged-in something in the nature of surveillance lies at the heart of the UFO problem. That is the hypothesis that my own study of the UFO problem leads me to regard as most probable in terms of my present information. This is, like all scientific hypotheses, a working hypothesis to be accepted or rejected only on the basis of continuing investigation. Present evidence surely does not amount to incontrovertible proof of the extraterrestrial hypothesis. What I find scientifically dismaying is that, while a large body of UFO evidence now seems to point in no other direction than the extraterrestrial hypothesis, the profoundly important implications of that possibility are going unconsidered by the scientific community because this entire problem has been imputed to be little more than a nonsense matter unworthy of serious scientific attention. Those overtones have been generated almost entirely by scientists and others who have done essentially no real investigation of the problem-area in which they express such strong opinions. Science is not supposed to proceed in that manner, and this AAAS Symposium should see an end to such approaches to the UFO problem.

Put more briefly, doesn’t a UFO case like Lakenheath warrant more than a mere shrug of the shoulders from science?

Case 3.  Haneda Air Force Base, Japan, August 5-6, 1952.

Brief summary:   USAF tower operators at Haneda AFB observed an unusually bright bluish-white light to their NE, alerted the GCI radar unit at Shiroi, which then called for a scramble of an F94 interceptor after getting radar returns in same general area. GCI ground radar vectored the F94 to an orbiting unknown target, which the F94 picked up on its airborne radar. The target then accelerated out of the F94’s radar range after 90 seconds of pursuit that was followed also on the Shiroi GCI radar.

1.  Introduction:

The visual and radar sightings at Haneda AFB, Japan, on August 5-6, 1952, represent an example of a long-puzzling case, still carried as an unidentified case by Project Bluebook, at my latest check, and chosen for analysis in the Condon Report. In the latter, is putatively explained in terms of a combination of diffraction and mirage distortion of the star Capella, as far as the visual parts are concerned, while the radar portions are attributed to anomalous propagation. I find very serious difficulties with those “explanations” and regard them as typical of a number of rather casually advanced explanations of long-standing UFO cases that appear in the Condon Report. Because this case has been discussed in such books as those of Ruppelt, Keyhoe, and Hall, it is of particular interest to carefully examine case-details on it and then to examine the basis of the Condon Report’s explanation of it, as example of how the Condon Report disposed of old “classic cases.”

Haneda AFB, active during the Korean War, lay about midway between central Tokyo and central Yokohama, adjacent to Tokyo International Airport. The 1952 UFO incident began with visual sightings of a brilliant object in the northeastern sky, as seen by two control tower operators going on duty at 2330 LST (all times hereafter will be LST). It will serve brevity to introduce some coded name designations for these men and for several officers involved, since neither the Condon Report, nor my copies of the original Bluebook case-file show names (excised from latter copies in accordance with Bluebook practice on non-release of witness names in UFO cases):

  Coded Designation Identification
  Airman A One of two Haneda tower operators who first sighted light. Rank was A/3c.
  Airman B Second Haneda tower operator to first sight light. Rank was A/1c.
  Lt. A Controller on duty at Shiroi GCI unit up to 2400, 8/5/52. Rank was 1st Lt.
  Lt. B Controller at Shiroi after 0000, 8/6/52, also 1st Lt.
  Lt. P Pilot of scrambled F94, also 1st Lt.
  Lt. R Radar officer in F94, also 1st Lt.

Shiroi GCI Station, manned by the 528th AC&W (Aircraft Control and Warning) Group, lay approximately 20 miles NE of Haneda (specifically at 35 deg. 49′ N, 140 deg. 2′ E) and had a CPS-1 10-cm search radar plus a CPS 10-cm height-finding radar. Two other USAF facilities figure in the incident, Tachikawa AFB, lying just over 20 miles WNW of Haneda, and Johnson AFB, almost 30 miles NW of Waneda. The main radar incidents center over the north extremity of Tokyo Bay, roughly midway from central Tokyo to Chiba across the Bay.

The Bluebook case-file on this incident contains 25 pages, and since the incident predates promulgation of AFR200-2, the strictures on time-reporting, etc., are not here so bothersome as in the Lakenheath case of 1956, discussed above. Nevertheless, the same kind of disturbing internal inconsistencies are present here as one finds in most Bluebook case reports; in particular, there is a bothersome variation in times given for specific events in different portions of the case-file. One of these, stressed in the Condon Report, will be discussed explicitly below; but for the rest, I shall use those times which appear to yield the greatest over-all internal consistency. This will introduce no serious errors, since the uncertainties are mostly only 1 or 2 minutes and, except for the cited instance, do not alter any important implications regardless of which cited time is used. The over-all duration of the visual and radar sightings is about 50 minutes. The items of main interest occurred between 2330 and 0020, approximately.

Although this case involves both visual and radar observations of unidentified objects, careful examination does not support the view that the same object was ever assuredly seen visually and on radar at the same time, with the possible exception of the very first radar detection just after 2330. Thus it is not a “radar-visual” case, in the more significant sense of concurrent two-channel observations of an unknown object. This point will be discussed further in Section 5.

2.  Visual Observations:

a.   First visual detection.

At 2330, Airmen A and B, while walking across the ramp at Haneda AFB to go on the midnight shift at the airfield control tower, noticed an “exceptionally bright light” in their northeastern sky. They went immediately to the control tower to alert two other on-duty controllers to it and to examine it more carefully with the aid of the 7×50 binoculars available in the tower. The Bluebook case-file notes that the two controllers already on tower-duty “had not previously noticed it because the operating load had been keeping their attention elsewhere. “

b.   Independent visual detection at Tachikawa AFB.

About ten minutes later, according to the August 12, 1952, Air Intelligence Information Report (IR-35-52) in the Bluebook case-file; Haneda was queried about an unusually bright light by controllers at Tachikawa AFB, 21 miles to their WNW. IR-35-52 states: “The control tower at Tachikawa Air Force Base called Haneda tower at approximately 2350 to bring their attention to a brilliant white light over Tokyo Bay. The tower replied that it had been in view for some time and that it was being checked.”

This feature of the report is significant in two respects: 1) It indicates that the luminous source was of sufficiently unusual brilliance to cause two separate groups of Air Force controllers at two airfields to respond independently and to take alert-actions; and 2) More significantly, the fact that the Tachikawa controllers saw the source in a direction “over Tokyo Bay” implies a line-of-sight distinctly south of east. From Tachikawa, even the north end of the Bay lies to the ESE. Thus the intersection of the two lines of sight fell somewhere in the northern half of the Bay, it would appear. As will be seen later, this is where the most significant parts of the radar tracking occurred subsequently.

c. Direction, intensity, and configuration of the luminous source.

IR-35-52 contains a signed statement by Air man A, a sketch of the way the luminous source looked through 7-power binoculars, and summary comments by Capt. Charle”s J. Malven, the FEAF intelligence officer preparing the report for transmission to Bluebook.

Airman A’s own statement gives the bearing of the source as NNE; Malven summary specifies only NE. Presumably the witness’ statement is the more reliable, and it also seems to be given a greater degree of precision, whence a line-of-sight azimuth somewhere in the range of 25 to 35 deg. east of north appears to be involved in the Haneda sightings. By contrast, the Tachikawa sighting-azimuth was in excess of 90 deg. from north, and probably beyond 100 deg., considering the geography involved, a point I shall return to later.

Several different items in the report indicate the high intensity of the source. Airman A’s signed statement refers to it as “the intense bright light over the Bay.” The annotated sketch speaks of “constant brilliance across the entire area” of the (extended) source, and remarks on “the blinding effect from the brilliant light.” Malven’s summary even points out that “Observers stated that their eyes would fatigue rapidly when they attempted to concentrate their vision on the object,” and elsewhere speaks of “the brilliant blue-white light of the object.” Most of these indications of brightness are omitted from the Condon Report, yet bear on the Capella hypothesis in terms of which that Report seeks to dispose of these visual sightings.

Airman A’s filed statement includes the remark that “I know it wasn’t a star, weather balloon or Venus, because I compared it with all three.” This calls for two comments. First, Venus is referred to elsewhere in the case-file, but this is certainly a matter of confusion, inasmuch as Venus had set that night before about 2000 LST. Since elsewhere in the report reference is made to Venus lying in the East, and since the only noticeable celestial object in that sector at that time would have been Jupiter, I would infer that where “Venus” is cited in the case-file, one should read “Jupiter.” Jupiter would have risen near 2300, almost due east, with apparent magnitude -2.0. Thus Airman A’s assertion that the object was brighter than “Venus” may probably be taken to imply something of the order of magnitude -3.0 or brighter. Indeed, since it is most unlikely that any observer would speak of a -3.0 magnitude source as “blinding” or “fatiguing” to look at, I would suggest that the actual luminosity, at its periods of peak value (see below) must have exceeded even magnitude -3 by a substantial margin.

Airman A’s allusion to the intensity as compared with a “weather balloon” refers to the comparisons (elaborated below) with the light suspended from a pilot balloon released near the tower at 2400 that night and observed by the tower controllers to scale the size and brightness. This is a very fortunate scaling comparison, because the small battery-operated lights long used in meteorological practice have a known luminosity of about 1.5 candle. Since a 1-candle source at 1 kilometer yields apparent magnitude 0.8, inverse-square scaling for the here known balloon distance of 2000 feet (see below) implies an apparent magnitude of about -0.5 for the balloon-light as viewed at time of launch. Capt. Malven’s summary states, in discussing this quite helpful comparison, “The balloon’s light was described as extremely dim and yellow, when compared to the brilliant blue white light of the object.” Here again, I believe one can safely infer an apparent luminosity of the object well beyond Jupiter’s -2.0. Thus, we have here a number of compatible indications of apparent brightness well beyond that of any star, which will later be seen to contradict explanations proposed in the Condon Report for the visual portions of the Haneda sightings.

Of further interest relative to any stellar source hypothesis are the descriptions of the configuration of the object as seen with 7-power binoculars from the Haneda tower, and its approximate angular diameter. Fortunately, the latter seems to have been adjudged in direct comparison with an object of determinate angular subtense that was in view in the middle of the roughly 50-minute sighting. At 2400, a small weather balloon was released from a point at a known distance of 2000 ft from the control tower. Its diameter at release was approximately 24 inches. (IR-35-52 refers to it as a “ceiling balloon”, but the cloud-cover data contained therein is such that no ceiling balloon would have been called for. Furthermore, the specified balloon mass, 30 grams, and diameter, 2 ft, are precisely those of a standard pilot balloon for upper-wind measurement. And finally, the time [2400 LST = 1500Z] was the standard time for a pilot balloon run, back in that period.) A balloon of 2-ft diameter at 2000-ft range would subtend 1 milliradian, or just over 3 minutes of arc, and this was used by the tower observers to scale the apparent angular subtense of the luminous source. As IR-35-52 puts it: “Three of the operators indicated the size of the light, when closest to the tower, was approximately the same as the small ceiling balloons (30 grams, appearing 24 inches in diameter) when launched from the weather station, located at about 2000 ft from the tower. This would make the size of the central light about 50 ft in diameter, when at the 10 miles distance tracked by GCI…. A lighted weather balloon was launched at 2400 hours…” Thus, it would appear that an apparent angular subtense close to 3 minutes of arc is a reasonably reliable estimate for the light as seen by naked eye from Haneda. This is almost twice the average resolution-limit of the human eye, quite large enough to match the reported impressions that it had discernible extent, i.e., was not merely a point source.

See also  1997: The Afterglow of the UFO Abduction Experience

But the latter is very much more clearly spelled out, in any event, for IR-35-52 gives a fairly detailed description of the object’s appearance through 7-power binoculars. It is to be noted that, if the naked-eye diameter were about 3 minutes, its apparent subtense when viewed through 7X-binoculars would be about 20 minutes, or two-thirds the naked-eye angular diameter of the full moon — quite large enough to permit recognition of the finer details cited in IR-35-52, as follows: “The light was described as circular in shape, with brilliance appearing to be constant across the face. The light appeared to be a portion of a large round dark shape which was about four times the diameter of the light. When the object was close enough for details to be seen, a smaller, less brilliant light could be seen at the lower left hand edge, with two or three more dim lights running in a curved line along the rest of the lower edge of the dark shape. Only the lower portion of the darker shape could be determined, due to the lighter sky which was believed to have blended with the upper side of the object. No rotation was noticed. No sound was heard.”

Keeping in mind that those details are, in effect, described for an image corresponding in apparent angular size to over half a lunar diameter, the detail is by no means beyond the undiscernible limit. The sketch included with IR-35-52 matches the foregoing description, indicating a central disc of “constant brilliance across entire area (not due to a point source of light)”, an annular dark area of overall diameter 3-4 times that of the central luminary, and having four distinct lights on the lower periphery, “light at lower left, small and fairly bright, other lights dimmer and possibly smaller.” Finally, supportive comment thereon is contained in the signed statement of Airman A. He comments: “After we got in the tower I started looking at it with binoculars, which made the object much clearer. Around the bright white light in the middle, there was a darker object which stood out against the sky, having little white lights along the outer edge, and a glare around the whole thing.”

All of these configurational details, like the indications of a quite un-starlike brilliance, will be seen below to be almost entirely unexplainable on the Capella hypothesis with which the Condon Report seeks to settle the Haneda visual sightings. Further questions ultimately arise from examination of reported apparent motions of the luminous source, which will be considered next.

d.   Reported descriptions of apparent motions of the luminous source.

Here we meet the single most important ambiguity in the Haneda case-file, though the weight of the evidence indicates that the luminous object exhibited definite movements. The ambiguity arises chiefly from the way Capt. Malven summarized the matter in his IR-35-52 report a week after the incident; “The object faded twice to the East, then returned. Observers were uncertain whether disappearance was due to a dimming of the lights, rotation of object, or to the object moving away at terrific speed, since at times of fading the object was difficult to follow closely, except as a small light. Observers did agree that when close, the object did appear to move horizontally, varying apparent position and speed slightly.” Aside from the closing comment, all of Malven’s summary remarks could be interpreted as implying either solely radial motion (improbable because it would imply the Haneda observers just happened to be in precisely the spot from which no crosswise velocity component could be perceived) or else merely illusion of approach and recession due to some intrinsic or extrinsic time-variation in apparent brightness.

In contrast to the above form in which Malven summarized the reported motions, the way Airman A described them in his own statement seems to refer to distinct motions, including transverse components: “I watched it disappear twice through the glasses. It seemed to travel to the East and gaining altitude at a very fast speed, much faster than any jet. Every time it disappeared it returned again, except for the last time when the jets were around. It seemed to know they were there. As for an estimate of the size of the object — I couldn’t even guess.” Recalling that elsewhere in that same signed statement this tower controller had given the observed direction to the object as NNE, his specification that the object “seemed to travel to the East” seems quite clearly to imply a non radial motion, since, if only an impression of the latter were involved, one would presume he would have spoken of it in some such terms as “climbing out rapidly to the NNE”. Since greater weight is presumably to be placed on direct-witness testimony than on another’s summary thereof, it appears necessary to assume that not mere radial recession but also transverse components of recession. upwards and towards the East, were observed.

That the luminous source varied substantially in angular subtense is made very clear at several points in the case-file: One passage already cited discusses the “size of the light, when closest to the tower…”, while, by contrast, another says that: “At the greatest distance, the size of the light appeared slightly larger than Venus, approximately due East of Haneda, and slightly brighter.” (For “Venus” read “Jupiter” as noted above. Jupiter was then near quadrature with angular diameter of around 40 seconds of arc. Since the naked eye is a poor judge of comparative angular diameters that far below the resolution limit, little more can safely be read into that statement than the conclusion that the object’s luminous disc diminished quite noticeably and its apparent brightness fell to a level comparable to or a bit greater than Jupiter’s when at greatest perceived distance. By virtue of the latter, it should be noted, one has another basis for concluding that when at peak brilliance it must have been considerably brighter than Jupiter’s -2.0, a conclusion already reached by other arguments above.

In addition to exhibiting what seems to imply recession, eastward motion, and climb to disappearance, the source also disappeared for at least one other period far too long to be attributed to any scintillation or other such meteorological optical effect: “When we were about half way across the ramp (Airman A stated), it disappeared for the first time and returned to approximately the same spot about 15 seconds later.” There were scattered clouds over Haneda at around 15-16,000 ft, and a very few isolated clouds lower down, yet it was full moon that night and, if patches of clouds had drifted very near the controllers’ line-of-sight to the object, they could be expected to have seen the clouds. (The upper deck was evidently thin, for Capt. Malven notes in his report that “The F94 crew reported exceptional visibility and stated that the upper cloud layer did not appreciably affect the brilliancy of the moonlight.”) A thin cloud interposed between observer and a distant luminous source would yield an impression of dimming and enhanced effective angular diameter, not dimming and reduced apparent size, as reported here. I believe the described “disappearances” cannot, in view of these several considerations, reasonably be attributed to cloud effects.

I have now summarized the essential features of the Haneda report dealing
with just the visual observations of some bright luminous source that
initiated the alert and that led to the ground-radar and air borne-radar
observations yet to be described. Before turning to those, which comprise, in
fact, the more significant portion of the over-all sighting, it will be best
to turn next to a critique of the Blue book and the Condon Report attempts to
give an explanation of the visual portions of the sighting.

3. Bluebook Critique of the Visual Sightings:

In IR-35-52. Capt, Malven offers only one hypothesis, and that in only passing manner: He speculates briefly on whether “reflections off the water (of the Bay, I presume) were…sufficient to form secondary reflections off the lower clouds,” and by the latter he refers to “isolated patches of thin clouds reported by the F-94 crew as being at approximately 4000 feet…” He adds that “these clouds were not reported to be visible by the control tower personnel,” which, in view of the 60-mile visibility cited elsewhere in the case-file and in view of the full moon then near the local meridian, suggests that those lower clouds must have been exceedingly widely scattered to escape detection by the controllers.

What Malven seems to offer there, as an hypothesis for the observed visual source, is cloud-reflection of moonlight — and in manner all too typical of many other curious physical explanations one finds scattered through Bluebook case-files, he brings in a consideration that reveals lack of appreciation of what is central to the issue. If he wants to talk about cloud-reflected moonlight, why render a poor argument even weaker by invoking not direct moon light but moonlight secondarily reflected off the surface of Tokyo Bay? Without even considering further that odd twist in his tentative hypothesis, it is sufficient to note that even direct moonlight striking a patch of cloud is not “reflected in any ordinary sense of that term. It is scattered from the cloud droplets and thereby serves not to create any image of a discrete light source of blinding intensity that fatigues observers’ eyes and does the other things reported by the Haneda observers, but rather serves merely to palely illuminate a passing patch of cloud material. A very poor hypothesis.

Malven drops that hypothesis without putting any real stress on it (with judgment that is not always found where equally absurd “explanations” have been advanced in innumerable other Bluebook case-files by reporting officers or by Bluebook staff members). He does add that there was some thunderstorm activity reported that night off to the northwest of Tokyo, but mentions that there was no reported electrical activity therein. Since the direction is opposite to the line of sight and since the reported visual phenomena bear no relation to lightning effects, this carried the matter no further, and the report drops that point there.

Finally, Malven mentions very casually an idea that I have encountered repeatedly in Bluebook files yet nowhere else in my studies of atmospheric physics, namely, “reflections off ionized portions of the atmosphere.” He states: “Although many sightings might be attributed to visual and electrical reflections off ionized areas in the atmosphere, the near-perfect visibility on the night of the sighting, together with the circular orbit of the object would tend to disprove this theory.” Evidently he rejects the “ionized areas” hypothesis on the ground that presence of such areas is probably ruled out in view of the unusually good visibility reported that night. I trust that, for most readers of this discussion, I would only be belaboring the obvious to remark that Bluebook mythology about radar and visual “reflections” off “ionized regions” in the clear atmosphere (which mythology I have recently managed to trace back even to pre-1950 Air Force documents on UFO reports) has no known basis in fact, but is just one more of the all too numerous measures of how little scientific critique the Air Force has managed to bring to bear on its UFO problems over the years.

Although the final Bluebook evaluation of this entire case, including the visual portions, was and is “Unidentified”, indicating that none of the above was regarded as an adequate explanation of even the visual features of the report, one cannot overlook extremely serious deficiencies in the basic reporting and the interrogation and follow-up here. This incident occurred in that period which my own studies lead me to describe as sort of a high water mark for Project Bluebook. Capt. Edward J. Ruppelt was then Bluebook Officer at Wright-Patterson AFB, and both he and his superiors were then taking the UFO problem more seriously than it was taken by USAF at any other time in the past 22 years. Neither before nor after 1952-3 were there as many efforts made to assemble case-information, to go out and actually check in the field on sightings, etc. Yet it should be uncomfortably apparent already at this point in this discussion of the Haneda case that quite basic points were not run to ground and pinned down. Ruppelt, in his 1956 book, speaks of this Haneda case as if it were regarded as one of the most completely reported cases they’d received as of mid-1952. He mentioned that his office sent a query to FEAF offices about a few points of confusion, and that the replies came back with impressive promptness, etc. If one needed some specific clue to the regrettably low scientific level of the operation of Bluebook even during this period of comparatively energetic case-investigation, one can find it in study of the Haneda report. Even so simple a matter as checking whether Venus was actually in the East was obviously left undone; and numerous cross-questions and followup queries on motions, angles, times, etc., not even thought of. That, I stress, is what any scientist who studies the Bluebook files as I have done will find all through 22 years of Air Force handling of the UFO problem. Incompetence and superficiality — even at the 1952 high water mark under Ruppelt’s relatively vigorous Project-direction.

4. Condon Report Critique of the Visual Sightings:

On p. 126 of the Condon Report, the luminous source discussed above is explained as a diffracted image of the star Capella: “The most likely source to have produced the visual object is the star Capella (magnitude 0.2), which was 8 deg. above horizon at 37 deg. azimuth at 2400 LST. The precise nature of the optical propagation mechanism that would have produced such a strangely diffracted image as reported by the Haneda AFB observers must remain conjectural.”

Suggesting that perhaps “a sharp temperature inversion may have existed at the top of (an inferred) moist layer, below which patches of fog or mist could collect,” the Report continues as follows: “The observed diffraction pattern could have been produced by either (1) interference effects associated with propagation within and near the top of an inversion, or (2) a corona with a dark aureole produced by a mist of droplets of water of about 0.2 mm diameter spaced at regular intervals is described by Minnaert (1954). In either event, the phenomenon must be quite rare. The brightness of the image may have been due in part to ‘Raman brightening’ of an image seen through an inversion layer.”

And in the final paragraph discussing this case, the Condon Report merely rounds it off to: “In summary , it appears that the most probable causes of this UFO report are an optical effect on a bright light source that produced the visual sighting…” (and goes on to a remark on the radar portions we have yet to examine here) .

There are some very serious difficulties with the more specific parts of the suggested explanation, and the vagueness of the other parts is sufficiently self-evident to need little comment.

First, nothing in the literature of meteorological optics discusses any diffraction-produced coronae with a dark annular space extending out to three or four diameters of the central luminary, such as is postulated in the above Condon Report explanation. The radial intensity pattern of a corona may be roughly described as a damped oscillatory radial variation of luminosity, with zero intensity minima (for the simple case of a monochromatic luminary) at roughly equal intervals, and no broad light-free annulus comparable to that described in detail by the Haneda controllers. Thus, lack of understanding of the nature of coronae is revealed at the outset in attempting to fit the Haneda observations to such a phenomenon.

Second, droplets certainly do not have to be “spaced at regular intervals” to yield a corona, and Minnaert’s book makes no such suggestion, another measure of misunderstanding of the meteorological optics here concerned. Nor is there any physical mechanism operating in clouds capable of yielding any such regular droplet spacing. Both Minnaert and cloud physics are misunderstood in that passage.

Third, one quickly finds, by some trial calculations, using the familiar optical relation (Exner equation) for the radial positions of the minima of the classical corona pattern, that the cited drop diameter of 0.2 mm = 200 microns was obtained in the Condon Report by back-calculating from a tacit requirement that the first-order minimum lay close to 3 milliradians, for these are the values that satisfy the Exner equation for an assumed wavelength of about 0.5 microns for visible light. This discloses even more thorough misunderstanding of corona optics, for that first-order minimum marks not some outer edge of a broad dark annulus as described and sketched by the Haneda tower operators, but the outer edge of the innermost annulus of high intensity of diffracted light. This clearly identifies basic misunderstanding of the matters at hand.

Fourth, the just-cited computation yielded a droplet diameter of 200 microns, which is so large as to be found only in drizzling or raining clouds and never in thin scattered clouds of the sort here reported, clouds that scarcely attenuated the full moon’s light. That is, the suggestion that “patches of fog or mist” collected under an hypothesized inversion could grow droplets of that large size is meteorologically out of the question. If isolated patches of clouds interposed themselves on an observer’s line of sight to some distant luminary, under conditions of the sort prevailing at Haneda that night, drop diameters down in the range of 10-20 microns would be the largest one could expect, and the corona-size would be some 10 to 20 times greater than the 3 milliradians which was plugged into the Exner equation in the above-cited computation. And this would, of course, not even begin to match anything observed that night.

Fifth, the vague suggestion that “Raman brightening” or other “interference effects associated with propagation within and near the top of an inversion” is involved here makes the same serious error that is made in attempted optical explanations of other cases in the Condon Report. Here we are asked to consider that light from Capella, whose altitude was about 8 deg. above the NE horizon (a value that I confirm) near the time of the Haneda observations, was subjected to Raman brightening or its equivalent; yet one of the strict requirements of all such interference effects is that the ray paths impinge on the inversion surface at grazing angles of incidence of only a small fraction of a degree. No ground observer viewing Capella at 8 deg. elevation angle could possibly see anything like Raman brightening, for the pertinent angular limits would be exceeded by one or two orders of magnitude. Added to this measure of misunderstanding of the optics of such interference phenomena in this attempted explanation is the further difficulty that, for any such situation as is hypothesized in the Condon Report explanation, the observer’s eye must be physically located at or directly under the index-discontinuity, which would here mean up in the air at the altitude of the hypothesized inversion. But all of the Haneda observations were made from the ground level. Negation of Raman brightening leaves one more serious gap in the Capella hypothesis, since its magnitude of 0.2 lies at a brightness level well below that of Jupiter, yet the Haneda observers seem to have been comparing the object’s luminosity to Jupiter’s and finding it far brighter, not dimmer.

Sixth, the Condon Report mentions the independent sighting from Tachikawa AFB, but fails to bring out that the line of sight from that observing site (luminary described as lying over Tokyo Bay, as seen from Tachikawa) pointed more than 45 deg. away from Capella, a circumstance fatal to fitting the Capella hypothesis to both sightings. Jupiter lay due East, not “over Tokyo Bay” from Tachikawa, and it had been rising in the eastern sky for many days, so it is, in any event, unlikely to have suddenly triggered an independent response at Tachikawa that night. And, conversely, the area intersection of the reported lines of sight from Haneda and Tachikawa falls in just the North Bay area where Shiroi GCI first got radar returns and where all the subsequent radar activity was localized.

Seventh, nothing in the proffered explanations in the Condon Report confronts the reported movements and disappearances of the luminous object that are described in the Bluebook case-file on Haneda. If, for the several reasons offered above, we conclude that not only apparent radial motions, but also lateral and climbing motions were observed, neither diffraction nor Raman effects can conceivably fit them.

Eighth, the over-all configuration as seen through 7X binoculars, particularly with four smaller lights perceived on the lower edge of the broad, dark annulus, is not in any sense explained by the ideas qualitatively advanced in the Condon Report on the weak basis now remarked.

Ninth, the Condon Report puts emphasis on the point that, whereas Haneda and Tachikawa observers saw the light, airmen at the Shiroi GCI site went outside and looked in vain for the light when the plotted radar position showed one or more targets to their south or south-southeast. This is correct. But we are quite familiar with both highly directional and semi-directional light sources on our own technological devices, so the failure to detect a light from the Shiroi side does not very greatly strengthen the hypothesis that Capella was the luminary in the Haneda visual sightings. The same can be said for lack of visual observations from the F-94, which got only radar returns as it closed on its target,

I believe that it is necessary to conclude that the “explanation” proposed in the Condon Report for the visual portions of the Haneda case are almost wholly unacceptable. And I remark that my analysis of many other explanations in the Condon Report finds them to be about equally weak in their level of scientific argumentation. We were supposed to get in the Condon Report a level of critique distinctly better than that which had come from Bluebook for many years; but much of the critique in that Report is little less tendentious and ill-based than that which is so dismaying in 22 years of Air Force discussions of UFO cases. The above stands as only one illustration of the point I make there; many more could be cited.

Next we must examine the radar aspects of the 8/5-6/52 Haneda case.

5.  Radar Observations:

Shortly after the initial visual sighting at Haneda, the tower controllers alerted the Shiroi GCI radar unit (located about 15 miles NE of central Tokyo), asking them to look for a target somewhere NE of Haneda at an altitude which they estimated (obviously on weak grounds) to be somewhere between 1500 and 5000 feet, both those figures appearing in the Bluebook case-file. Both a CPS-1 search radar and a CPS-4 height-finder radar were available at Shiroi, but only the first of those picked up the target, ground clutter interference precluding useful CPS-4 returns. The CPS-1 radar was a 10-cm, 2-beam set with peak power of 1 megawatt, PRF of 400/sec, antenna tilt 3 deg., and scan-rate operated that night at 4 rpm. I find no indication that it was equipped with MTI, but this point is not certain.

It may help to keep the main sequence of events in better time order if I first put down the principal events that bear on the radar sightings from ground and air, and the times at which these events occurred. In some instances a 1-2 minute range of times will be given because the case-file contains more than a single time for that event as described in separate sections of the report. I indicate 0015-16 LST (all times still LST) as the time of first airborne radar contact by the F-94, and discuss that matter in more detail later, since the Condon Report suggests a quite different time.

  Time  (LST) Events
  2330 Tower controllers at Haneda see bright light to NE, call Shiroi GCI within a few minutes thereafter.
  2330-45 Lt. A, Shiroi radar controller on evening watch, looks for returns, finds 3-4 stationary blips to NE of Haneda on low beam of CPS-1.
  2345 Lt. B comes on duty for midwatch at Shiroi, he and Lt. A discuss possible interceptor scramble.
  2355 Lt. A calls Johnson AFB, asks for F-94 scramble. Fuel system trouble causes delay of 5-10 min in the scramble.
  0001 Lt. B has unknown in right orbit at varying speeds over north Tokyo Bay, 8 miles NE of Haneda. Loses contact again.
  0003-04 F-94 airborne out of Johnson AFB, Lt. P as pilot, Lt. R, radarman.
  0009-10 Shiroi alerts F-94 to airborne target to its starboard as it heads down Tokyo Bay, and Lt. p visually identifies target as C-54 in pattern to land at Haneda. Lt. B instructs Lt. P to begin search over north Bay area at flight altitude of 5000 ft.
  0012 Shiroi regains CPS-1 contact on unknown target in right orbit over same general area seen before, target splits into three separate targets, and Lt. B vectors F-94 towards strongest of three returns.
  0015-16 F-94 gets airborne radar contact on moving target at range and bearing close to vector information, has to do hard starboard turn to keep on scope as target moves with acceleration across scope.
  0017-18 After 90 seconds pursuit, with no lock-on achieved, target moves off scope at high speed, Shiroi GCI tracks both unknown and F-94 into its ground clutter, where both are then lost in clutter.
  0033 Shiroi releases F-94 from scramble-search.
  0040 F-94 visually spots another C-54, over Johnson.
  0120 P-94  lands back at Johnson

Thus the period 2330 on 8/5 through about 0018 on 8/6 is of present interest:  Next, events in that period will be examined in closer detail.

a.  Initial attempts at radar detection from Shiroi GCI.

When, at about 2335 or so, Haneda requested Shiroi to search the area of the bay to the NE of Haneda (SSW from Shiroi, roughly), Lt. A, then duty controller at Shiroi, found his CPS-4 giving too much ground clutter to be useful for the relatively low estimated heights Haneda had suggested. Those heights are indicated as 1500-2000 ft in one portion of the case file, though Airman A elsewhere gave 5000 ft as his impression of the height. Clearly, lack of knowledge of size and slant ranges precluded any exact estimates from Haneda, but they offered the above indicated impressions.

Trying both low and high beams on the CPS-1 search radar, Lt. A did detect three or four blips “at a position 050 deg. bearing from Haneda, as reported by the tower, but no definite movement could be ascertained…” The report gives no information on the range from Shiroi, nor inferred altitude of those several blips, only the first of a substantial number of missing items of quite essential information that were not followed up in any Bluebook inquiries, as far as the case-file shows. No indication of the spacing of the several targets is given either, so it is difficult to decide whether to consider the above as an instance of “radar visual” concurrency or not. One summary discussion in the Bluebook case-file so construes it: “The radar was directed onto the target by visual observations from the tower. So it can safely be assumed that both visual and radar contacts involved the same object.” By contrast, the Condon Report takes the position that there were no radar observations that ever matched the visual observations. The latter view seems more justified than the former, although the issue is basically unresolvable. One visual target won’t, in any event, match 3-4 radar targets, unless we invoke the point that later on the main radar target split up into three separate radar targets, and assume that at 2335, 3-4 unknown objects were airborne and motionless, with only one of these luminous and visually detectable from Haneda. That is conceivable but involves too strained assumptions to take very seriously; so I conclude that, even in this opening radar search, there was not obvious correspondence between visual and radar unknowns. As we shall see, later on there was definitely not correspondence, and also the F-94 crew never spotted a visual target. Thus, Haneda cannot be viewed as a case involving the kind of “radar-visual” concurrency which does characterize many other important cases. Nonetheless, both the visual and the radar features, considered separately, are sufficiently unusual in the Haneda case to regard them as mutually supporting the view that inexplicable events were seen and tracked there that night.

One may ask why a radar-detected object was not seen visually, and why a luminous object was not detected on search radar; and no fully satisfactory answer lies at hand for either question. It can only be noted that there are many other such cases in Bluebook files and that these questions stand as part of the substantial scientific puzzle that centers around the UFO phenomena. We know that light-sources can be turned off, and we do know that ECM techniques can fool radars to a certain extent. Thus, we might do well to maintain open minds when we come to these questions that are so numerous in UFO case analyses.

b. F-94 scramble.

When Lt. B came on duty at 2345, he was soon able, according to Capt. Malven’s summary in IR-35-52, “to make radar contact on the 50-mile high beam,” whereupon he and Lt. A contacted the ADCC flight controller at Johnson AFB 35 miles to their west, requesting that an interceptor be scrambled to investigate the source of the visual and the radar sightings.

An F-94B of the 339th Fighter-Interceptor Squadron, piloted by Lt. P, with Lt. R operating the APG-33 air-intercept radar, was scrambled, though a delay of over ten minutes intervened because of fuel-system difficulties during engine runup. The records show the F-94 airborne at about 0003-04, and it then took about 10 minutes to reach the Tokyo Bay area. The APG-33 set was a 3-cm (X-band) set with 50 KW power, and lock-on range of about 2500 yards, according to my information. The system had a B-scope, i.e., it displayed target range vs. azimuth. The case-file notes that: “The APG-33 radar is checked before and after every mission and appeared to be working normally.”

At 0009, Shiroi picked up a moving target near Haneda and alerted the F-94 crew, who had no difficulty identifying it visually as an Air Force C-54 in the Haneda pattern. The crew is quoted in the report as reporting “exceptional visibility.” Shiroi instructed the F-94 to begin searching at 5000 ft altitude as it got out over the Bay. But before proceeding with events of that search, a GCI detection of a moving target at about 0001 must be reviewed.

c.  First GCI detection of orbiting object.

Just before the F-94 became airborne out of Johnson AFB, Lt. B picked up the first definitely unusual moving target, at about 0000-01. His statement in the Bluebook case-file reads: “At the time of the scramble, I had what was believed to be the object in radar contact. The radar sighting indicated the object to be due south of this station over Tokyo Bay and approximately eight (8) miles northeast of Haneda. The target was in a right orbit moving at varying speeds. It was impossible to estimate speed due to She short distance and times involved.” That passage is quoted in the Condon Report, but not the next, which comes from Malven’s summary and indicates that Lt. B only meant that it was impossible to estimate the target’s speed with much accuracy. The omitted passage is interesting, for it is one of a number of indications that anomalous propagation (which is the Condon Report’s explanation for the radar sightings) is scarcely creditable: “An F-94 was scrambled to investigate. The object at this time had left the ground clutter and could be tracked (on the CPS-1) at varying speeds in a right orbit. Although impossible to accurately estimate speed, Lt. B gave a rough estimate of 100-150 knots, stopping, and hovering occasionally, and a maximum speed during the second orbit (just before F-94 was vectored in) of possibly 250-300 knots.”

A map accompanying IR-35-52 shows the plotted orbiting path of the unknown target. The orbit radius is approximately 4 miles, centered just off the coast from the city of Funabashi, east of Tokyo. The orbiting path is about half over land, half over water. The map sketch, plus the file comments, imply that GCI had good contacts with the target only while it was moving out over the Bay. The ground-clutter pattern of the CPS-1 is plotted on the same map (and on other maps in the file), and it seems clear that the difficulty in tracking the target through the land portion of the roughly circular orbit was that most of that portion lay within the clutter area. The presumption is strong that this set did not have MTI, which is unfortunate.

The circumference of the orbit of about 4-mi radius would be about 25 miles. Taking Lt. B’s rough estimate of 100-150 knots in the first of the two circuits of this orbit (i.e., the one he detected at about 0001), a total circuit-time of perhaps 12-13 minutes is indicated. Although the basis for this time-estimate is quite rough, it matches reasonably well the fact that it was about 0012 when it had come around again, split up into three targets, and looped onshore again with the F-94 in pursuit this time.

If the object executing the above orbits had been the luminous object being watched from Haneda, it would have swung back and forth across their sky through an azimuth range of about 30 deg. Since no such motion seems to have been noted by the Haneda observers, I believe it must be concluded that the source they watched was distinct from the one radar-tracked in orbit.

d.  Second orbit and F-94 intercept attempt.

The times given in Lt. B’s account of this phase of the sighting do not match those given by the pilot and radarman of the F-94 in their signed statements in the file. Other accounts in the file match those of the aircrew, but not the times in Lt. B’s summary. This discrepancy (about 10-12 minutes) is specifically noted in Capt. Malven’s IR-35-52 summary: “The ten minute difference in time between the statement by Lt. B, 528th ACGW SQ, and that reported by other personnel concerned, is believed to be a typographical error, since the statement agrees on every other portion of the sighting.” That Lt. B and the aircrew were describing one and the same intercept seems beyond any doubt; and in view of Malven’s quoted comment, I here use the times recorded by the aircrew and accepted as the correct times in other parts of the case-file. Further comment on this will be given below.

After completing the first of the two orbits partially tracked by GCI Shiroi, the target came around again where it was out of the CPS-1 ground-clutter pattern, and Lt. B regained contact. Malven’s summary comments on the next developments as follows: “At 0012 the object reportedly broke into three smaller contacts, maintaining an interval of about 1/4 miles, with one contact remaining somewhat brighter. The F-94 was vectored on this object, reporting weak contact at 1500 and loss of contact at 0018. Within a few seconds, both the F-94 and the object entered the ground clutter and were not seen again.”

The same portion of the incident is summarized in Lt. B’s account (with different times), with the F-94 referred to by its code-name “Sun Dial 20.” Immediately following the part of his account referring to the first starboard orbit in which he had plotted the target’s movements, at around 0001, comes the following section: “Sun Dial 20 was ordered to search the Tokyo Bay area keeping a sharp lookout for any unusual occurrences. The object was again sighted by radar at 0017 on a starboard orbit in the same area as before. Sun Dial 20 was vectored to the target. He reported contact at 0025 and reported losing contact at 0028. Sun Dial 20 followed the target into our radar ground clutter area and we were unable to give Sun Dial 20 further assistance in re-establishing contact. Sun Dial 20 again resumed his visual search of the area until 0014, reporting negative visual sighting on this object at any time.” If Malven’s suggestion of typographical error is correct, the in-contact times in the foregoing should read 0015 and 0018, and presumably 0017 should be 0012. But regardless of the precise times, the important point is that Lt. B vectored the F-94 into the target, contact was thereby achieved, and Lt. B followed the target and pursuing F-94 northeastward into his ground clutter. I stress this because, in the Condon Report, the matter of the different times quoted is offered as the sole basis of a conclusion that ground radar and airborne radar were never following the same target. This is so clearly inconsistent with the actual contents of the case-file that it is difficult to understand the Report rationale.

Even more certain indication that the GCI radar was tracking target and F-94 in this crucial phase is given in the accounts prepared and signed by the pilot and his radarman. Here again we meet a code-designation, this time “Hi-Jinx”, which was the designation for Shiroi GCI used in the air-to-ground radio transmissions that night and hence employed in these next two accounts. The F-94 pilot, Lt. P states: “The object was reported to be in the Tokyo Bay area in an orbit to the starboard at an estimated altitude of 5,000 feet. I observed nothing of an unusual nature in this area; however, at 0016 when vectored by Hi-Jinx on a heading of 320 degrees, and directed to look for a bogie at 1100 o’clock, 4 miles, Lt. R made radar contact at 10 degrees port, 6000 yards. The point moved rapidly from port to starboard and disappeared from the scope. I had no visual contact with the target.”

And the signed statement from the radarman, Lt. R, is equally definite about these events: “At 0015 Hi-Jinx gave us a vector of 320 degrees. Hi-Jinx had a definite radar echo and gave us the vector to intercept the unidentified target. Hi-Jinx estimated the target to be at 11 o’clock to us at a range of 4 miles. At 0016 I picked up the radar contact at 10 degrees port, 10 degrees below at 6,000 yards. The target was rapidly moving from port to starboard and a ‘lock on’ could not be accomplished. A turn to the starboard was instigated to intercept target which disappeared on scope in approximately 90 seconds. No visual contact was made with the unidentified target. We continued our search over Tokyo Bay under Hi-Jinx control. At 0033 Hi-Jinx released us from scrambled mission…”

Of particular importance is the very close agreement of the vectoring instructions given by Shiroi GCI to the F-94 and the actual relative position at which they accomplished radar contact; GCI said 4 miles range at the aircraft’s 11 o’clock position, and they actually got radar contact with the moving target at a 6000-yard range, 10 degrees to their port. Nearly exact agreement, and thus incontrovertibly demonstrating that ground-radar and airborne radar were then looking at the same moving unknown target, despite the contrary suggestions made in the Condon Report. Had the Condon Report presented all of the information in the case-file, it would have been difficult to maintain the curious position that is maintained all of the way to the final conclusion about these radar events in the Condon Report’s treatment of the Haneda case.

That the moving target, as seen by both ground and airborne radar was a distinct target, though exhibiting radar cross-section somewhat smaller than that typical of most aircraft, is spelled out in Malven’s IR-35-52 summary: “Lt.B, GCI Controller at the Shiroi GCI site, has had considerable experience under all conditions and thoroughly understands the capabilities of the CPS-1 radar. His statement was that the object was a bonafide moving target, though somewhat weaker than that normally obtained from a single jet fighter.” And, with reference to the airborne radar contact, the same report states; “Lt. R, F-94 radar operator, has had about seven years’ experience with airborne radar equipment. He states that the object was a bonafide target, and that to his knowledge, there was nothing within an area of 15-20 miles that could give the radar echo.” It is exceedingly difficult to follow the Condon Report in viewing such targets as due to anomalous propagation.

Not only were there no visual sightings of the orbiting target as viewed from the F-94, but neither were there any from the Shiroi site, though Lt. B specifically sent men out to watch as these events transpired. Also, as mentioned earlier, it seems out of the question to equate any of the Haneda visual observations to the phase of the incident just discussed. Had there been a bright light on the unknown object during the time it was in starboard orbit, the Haneda observers would almost certainly have reported those movements. To be sure, the case-file is incomplete in not indicating how closely the Haneda observers were kept in touch as the GCI directed radar-intercept was being carried out. But at least it is clear that the Haneda tower controllers did not describe motions of the intensely bright light that would fit the roughly circular starboard orbits of radius near four miles. Thus, we seem forced to conclude either that the target the F-94 pursued was a different one from that observed at Haneda (likely interpretation), or that it was non-luminous during that intercept (unlikely alternative, since Haneda observations did not have so large a period of non-visibility of the source they had under observation 2330-0020).

6. Condon Report Critique of the Radar Sightings:

The Bluebook case-file contains essentially no discussion of the radar events, no suggestion of explanations in terms of any electronic or propagational anomalies. The case was simply put in the Unexplained category back in 1952 and has remained in that category since then at Bluebook.

By contrast, the Condon Report regards the above radar events as attributable to anomalous propagation. Four reasons are offered (p. 126) in support of that conclusion;

1) The tendency for targets to disappear and reappear;

2) The tendency for the target to break up into smaller targets;

3) The apparent lack of correlation between the targets seen on the GCI and airborne radars;

4) The radar invisibility of the target when visibility was “exceptionally good.”

Each of these four points will now be considered.

First, the “tendency for the targets to disappear and reappear” was primarily a matter of the orbiting target’s moving into and out of the ground-clutter pattern of the CPS-1, as is clearly shown in the map that constitutes Enclosure #5 in the IR-35-52 report, which was at the disposal of the Colorado staff concerned with this case. Ground returns from AP (anomalous propagation) may fade in and out as ducting intensities vary, but here we have the case of a moving target disappearing into and emerging from ground clutter, while executing a roughly circular orbit some 4 miles in radius. I believe it is safe to assert that nothing in the annals of anomalous propagation matches such behavior. Nor could the Borden-Vickers hypothesis of “reflections” off moving waves on inversions fit this situation, since such waves would not propagate in orbits, but would, at best, advance with the direction and speed of the mean wind at the inversion. Furthermore, the indicated target speed in the final phases of the attempted intercept was greater than that of the F-94, i.e., over 400 knots, far above wind speeds prevailing that night, so this could not in any event be squared with the (highly doubtful) Borden-Vickers hypothesis that was advanced years ago to account for the 1952 Washington National Airport UFO incidents.

See also  Why Do Ufologists Largely Ignore the Most Scientific Field Study of UFOs Ever Conducted?

Second, the breakup of the orbiting target into three separate targets cannot fairly be referred to as a “tendency for the target to break up into smaller targets.” That breakup event occurred in just one definite instance, and the GCI controller chose to vector the F-94 onto the strongest of the resultant three targets. And when the F-94 initiated radar search in the specific area (11 o’clock at 4 miles) where that target was then moving, it immediately achieved radar contact. For the Condon Report to gloss over such definite features of the report and merely allude to all of this in language faintly suggestive of AP seems objectionable.

Third, to build a claim that there was “apparent lack of correlation between the targets seen on the GCI and airborne radars” on the sole basis of the mismatch of times listed by Lt. B on the one hand and by the aircrew on the other hand, to ignore the specific statement by the intelligence officer filing IR-35-52 about this being a typographical error on the part of Lt. B, and, above all, to ignore the obviously close correspondence between GCI and air borne radar targeting that led to the successful radar-intercept, and finally to ignore Lt. B’s statement that the F-94 “followed the target into our radar ground clutter”, all amount to a highly slanted assessment of case details, details not openly set out for the reader of the Condon Report to evaluate for himself. I believe that all of the material I have here extracted from the Haneda case file fully contradicts the third of the Condon Report four reasons for attributing the radar events to AP. I would suggest that it is precisely the impressive correlation between GCI and F-94 radar targeting on this non-visible, fast-moving object that constitutes the most important feature of the whole case.

Fourth, it is suggested that AP is somehow suspected because of “the radar invisibility of the target when visibility was ‘exceptionally good.'” This is simply unclear. The exceptional visibility of the atmosphere that night is not physically related to “radar invisibility” in any way, and I suspect this was intended to read “the invisibility of the radar target when visibility was exceptionally good.” As cited above, neither the Shiroi crew nor the F-94 crew ever saw any visible object to match their respective radar targets. Under some circumstances, such a situation would indeed be diagnostic of AP. But not here, where the radar target is moving at high speed around an orbit many miles in diameter, occasionally hovering motionless (see Malven’s account cited earlier), and changing speed from 100-150 knots up to 250-300 knots, and finally accelerating to well above an F-94’s 375-knot speed.

Thus, all four of the arguments offered in the Condon Report to support its claim that the Haneda radar events were due to anomalous propagation must be rejected. Those arguments seem to me to be built up by a highly selective extraction of details from the Bluebook case-file, by ignoring the limits of the kind of effects one can expect from AP, and by using wording that so distorts key events in the incident as to give a vague impression where the facts of the case are really quite specific.

It has, of course, taken more space to clarify this Haneda case than the case is given in the Condon Report itself. Unfortunately, this would also prove true of the clarification of some fifteen to twenty other UFO cases whose “explanation” in the Condon Report contains, in my opinion, equally objectionable features, equally casual glossing-over of physical principles, of important quantitative points. Equally serious omissions of basic case information mark many of those case discussions in the Condon Report. Here I have used Haneda only as an illustration of those points; but I stress that it is by no means unique. The Condon Report confronted a disappointingly small sample of the old “classic” cases, the long-puzzling cases that have kept the UFO question alive over the years, and those few that it did confront it explained away by argumentation as unconvincing as that which disposes of the Haneda AFB events in terms of diffraction of Capella and anomalous propagation. Scientifically weak argumentation is found in a large fraction of the case analyses of the Condon Report, and stands as the principal reason why its conclusions ought to be rejected.

Here are some other examples of UFO cases considered explained in the Condon Report for which I would take strong exception to the argumentation presented and would regard as both unexplained and of strong scientific interest (page numbers in Condon Report are indicated): Flagstaff, Ariz., 5/20/50 (p. 245); Washington, D. C., 7/19/52 (p. 153); Bellefontaine, O., 8/1/52 (p. 161); Gulf of Mexico, 12/6/52 (p. 148); Odessa, Wash., 12/10/52 (p. 140); Continental Divide, N.M., 1/26/53 (p. 143); Seven Isles, Quebec, 6/29/54 (p. 139); Niagara Falls, N.Y., 7/25/57 (p. 145); Kirtland AFB, N.M., 11/4/57 (p. 141); Gulf of Mexico, 11/5/57 (p. 165); Peru, 12/30/66 (p. 280); Holloman AFB, 3/2/67 (p. 150); Kincheloe AFB, 9/11/67 (p. 164); Vandenberg AFB, 10/6/67 (p. 353).

Case 4.   Kirtland AFB, November 4, 1957.

Brief summary: Two CAA control tower operators observe a lighted egg-shaped object descend to and cross obliquely the runway area at Kirtland AFB (Albuquerque), hover near the ground for tens of seconds, then climb at unprecedented speed into the overcast. On radar, it was then followed south some miles, where it orbited a number of minutes before returning to the airfield to follow an Air Force aircraft outbound from Kirtland.

1.   Introduction:

This case, discussed in the Condon Report on p. 141, is an example of a UFO report which had lain in Bluebook files for years, not known to anyone outside of Air Force circles.

Immediately upon reading it, I became quite curious about it; more candidly, I became quite suspicious about it. For, as you will note on reading it for yourself, it purports to explain an incident in terms of an hypothesis with some glaringly improbable assumptions, and makes a key assertion that is hard to regard as factual. Let me quote from the first descriptive paragraph: “Observers in the CAA (now FAA) control tower saw an unidentified dark object with a white light underneath, about the ‘shape of an automobile on end’, that crossed the field at about 1500 ft and circled as if to come in for a landing on the E-W runway. This unidentified object appeared to reverse direction at low altitude, while out of sight of the observers behind some buildings, and climbed suddenly to about 200-300 ft., heading away from the field on a 120 deg. course. Then it went into a steep climb and disappeared into the overcast.” The Condon Report next notes that; “The Air Force view is that this UFO was a small, powerful private aircraft, flying without flight plan, that became confused and attempted a landing at the wrong airport. The pilot apparently realized his error when he saw a brightly-lit restricted area, which was at the point where the object reversed direction…” The Report next remarks very briefly that the radar blip from this object was described by the operator as a “perfectly normal aircraft return”, that the radar tract “showed no characteristics that would have been beyond the capabilities of the more powerful private aircraft available at the time,” and the conclusion arrived at in the Condon Report, without further discussion, is that; “There seems to be no reason to doubt the accuracy of this analysis.”

2.   Some Suspect Features of the Condon Report’s Explanation

It seemed to me that there were several reasons “to doubt the accuracy of this analysis.” First, let me point out that the first line or two of the account in the Condon Report contains information that the incident took place with “light rain over the airfield”, late in the evening (2245-2305 MST), which I found to be correct, on checking meteorological records. Thus the reader is asked to accept the picture of a pilot coming into an unfamiliar airfield at night and under rain conditions, and doing a 180 deg. return at so low an altitude that it could subsequently climb suddenly to about 200-300 ft; and we are asked to accept the picture of this highly hazardous low-altitude nighttime turn being executed so sharply that it occurred “while out of sight of the observers behind some buildings.” Now these are not casual bystanders doing the observing, but CAA controllers in a tower designed and located to afford full view of all aircraft operations occurring in or near its airfield. Hence my reaction to all of this was a reaction of doubt. Pilots don’t live too long who execute strange and dangerous maneuvers of the type implied in this explanation. And CAA towers are not located in such a manner that “buildings” obscure so large a block of airfield-airspace as to permit aircraft to do 180 deg. turns while hidden from tower view behind them (at night, in a rain!).

3. Search for the Principal Witnesses:

The foregoing points put such strong a priori doubt upon the “private aircraft” explanation advanced in the Condon Report that I began an independent check on this case, just as I have been checking several dozen other Condon Report cases in the months since publication of the Report. Here, as in all other cases in the Report, there are no witness-names given to facilitate independent check, but by beginning my inquiries through the FAA, I soon got in touch with the two CAA tower observers, both of whom are still with FAA, one in Oklahoma, one in California. Concurrently, I initiated a number of inquiries concerning the existence of any structures back in 1957 that could have hidden an aircraft from tower view in the manner suggested by the Report. What I ultimately learned constitutes only one example of many that back up the statement I have been making recently to many professional groups: The National Academy of Sciences is going to be in a most awkward position when the full picture of the inadequacies of the Condon Report is recognized; for I believe it will become all too obvious that the Academy placed its weighty stamp on this dismal report without even a semblance of rigorous checking of its contents.

The two tower controllers, R. M. Kaser and E. G. Brink, with whom I have had a total of five telephone interviews in the course of clarifying the case, explained to me that the object was so unlike an aircraft and exhibited performance characteristics so unlike those of any aircraft flying then or now that the “private aircraft” explanation was quite amusing. Neither had heard of the Air Force explanation, neither had heard of the Condon Project concurrence therein, and, most disturbing of all, neither had ever heard of the Condon Project: No one on the Condon Project ever contacted these two men! A half-million-dollar Project, a Report filled with expensive trivia and matters shedding essentially no light on the heart of the UFO: puzzle, and no Project investigator even bothers to hunt down the two key witnesses in this case, so casually closed by easy acceptance of the Bluebook “aircraft” explanation.

Failure to locate those two men as part of the investigation of this case is all the more difficult to understand because CAA tower operators involved as witnesses of a UFO incident were actually on duty would seem to constitute just the type of witnesses one should most earnestly seek out in attempts to clarify the UFO puzzle. In various sections of the Condon Report, witness-shortcomings (lack of experience, lack of familiarity with observing things in the sky, basic lack of credibility, etc.) are lamented, yet here, where the backgrounds of the witnesses and the observing circumstances are highly favorable to getting reliable testimony, the Colorado group did not bother to locate the witnesses. (This is not an isolated example. Even in cases which were conceded to be Unexplained, such as the June 23, 1955 Mohawk Airlines multiple-witness sighting near Utica, N.Y. [p. 143 in Report], or the Jackson, Alabama, November 14, 1956 airline case, both conceded to be unexplained, I found on interviewing key witnesses as part of my cross-check on the Condon Report, that no one from Colorado had ever talked to the witnesses. In still other important instances, only a fraction of the available witnesses were queried in preparing the Condon Report. Suggestions that the Report was based on intensive investigatory work simply are not correct.)

4.  Information Gained from Witness-Interviews:

When I contacted Kaser and Brink, they told me I was the first person to query them on the case since their interrogation by an Air Force captain from Colorado Springs, who had come to interview them at Kirtland just after the incident. Subsequently, I secured the Bluebook case-file on this sighting, and ascertained that a Capt. Patrick O. Shere, from Ent AFB did the interrogation on Nov. 8, 1957, just four days after the sighting.

The accounts I secured in 1969 from Kaser and Brink matched impressively the information I found in Shere’s 1957 report in the Bluebook case-file. There were a few recollective discrepancies of distance or time estimates in the witness accounts given in 1969, as compared with their 1957 statements to the Air Force, but the agreements were far more significant than the small number of mismatches.

In contrast to the somewhat vague impressions I gained (and other readers would surely also gain) from reading the Condon Report version, here is what is in the Bluebook case-file and what they told me directly.

The object came down in a rather steep dive at the east end of Runway 26, left the flight line, crossed runways, taxiways and unpaved areas at about a 30-degree angle, and proceeded southwestward towards the CAA tower at an altitude they estimated at a few tens of feet above ground. Quickly getting 7x binoculars on it, they established that it had no wings, tail, or fuselage, was elongated in the vertical direction, and exhibited a somewhat eggshaped form (Kaser). It appeared to be perhaps 15-20 ft in vertical dimension, about the size of an automobile on end, and had a single white light in its base. Both men were emphatic in stressing to me that it in no way resembled an aircraft.

It came towards them until it reached a B-58 service pad near the northeast corner of Area D (Drumhead Area, a restricted area lying south of the E-W runway at Kirtland). That spot lay about 3000 ft ENE of the tower, near an old machine-gun calibration bunker still present at Kirtland AFB. There it proceeded to stop completely, hover just above ground in full view for a time that Kaser estimated at about 20 seconds, that Brink suggested to me was more like a minute, and that the contemporary Air Force interrogation implied as being rather more than a minute. Next they said it started moving again, still at very low altitude, Still at modest speed, until it-again reached the eastern boundary of the field. At that point, the object climbed at an extremely rapid rate (which Kaser said was far faster than that of such modern jets as the T-38).

The Bluebook report expresses the witness’ estimate of the climb rate as 45,000 ft/min, which is almost certainly a too-literal conversion from Mach 1. My phone-interview notes include a quote of Brink’s statement to me that, “There was no doubt in my mind that no aircraft I knew of then, or ever operating since then, would compare with it. ” Both men were emphatic in stating to me that at no time was this object hidden by any buildings. I confirmed through the Albuquerque FAA office that Area D has never had anything but chain-link fence around it, and that no buildings other than scattered one-story metal buildings ever existed either inside or outside Area D in that sector. The bunker is only about 15-20 feet high, judging from my own recent observations and photos of it from the air. The Bluebook interrogation report contains no statements hinting that the object was ever hidden from view by any structures (although the Bluebook file contains the usual number of internally inconsistent and confusingly presented details).

I asked both men whether they alerted anyone else while the foregoing events were taking place. They both indicated that the object was of such unprecedented nature that it wasn’t until it shot up into the overcast that they got on the phone to get the CAA Radar Approach Control (RAPCON) unit to look for a fast target to the east. Kaser recalled that a CPN-18 surveillance radar was in use at that RAPCON unit at that time, a point confirmed to me in subsequent correspondence with the present chief of the Albuquerque Airport Traffic Control Tower, Mr. Robert L. Behrens, who also provided other helpful information. Unfortunately, no one who was in the Albuquerque/Kirtland RAPCON unit in 1957 is now available, and the person whom Kaser thought was actually on the CPN-18 that night is now deceased. Thus I have only Kaser and Brink recollections of the radar-plotting of the unknown, plus the less than precise information in the Nov. 6, 1957 TWX to Bluebook. Capt. Shere did not, evidently, take the trouble to secure any information from radar personnel.

As seen on the RAPCON CPN-18, the unknown target was still moving in an easterly direction when the alert call came from the tower. It then turned southward, and as Kaser recalled, moved south at very high speed, though nothing is said about speed in the Kirtland TWX of Nov. 6, 1957. It proceeded a number of miles south towards the vicinity of the Albuquerque Low Frequency Range Station, orbited there for a number of minutes, came back north to near Kirtland, took up a trail position about a half-mile behind an Air Force C-46 just then leaving Kirtland, and moved offscope with the C-46. The Nov. 8, 1957 report from Commander, 34th Air Div. to ADC and to the Air Technical Intelligence Command closed with the rather reasonable comment: “Sighting and descriptions conform to no known criteria for identification of UFOs.” The followup report of Nov. 13, 1957, prepared by Air Intelligence personnel from Ent AFB, contains a number of relevant comments on the experience of the two witnesses (23 years of tower control work between them as of that date), and on their intelligence, closing with the remarks: “In the opinion of the interviewer, both sources (witnesses) are considered completely competent and reliable.”

5. Critique of the Evaluation in the Condon Report:

The Kirtland AFB case is a rather good (though not isolated) instance of the general point I feel obliged to make on the basis of my continuing check of the Condon Report: In it we have not been given anything superior to the generally casual and often incompetent level of case-analysis that marked Bluebook’s handling of the UFO problem in past years.

In the Bluebook files, this case is carried as “Possible Aircraft”. Study of the 21-page case-file reveals that this is based solely on passing comment made by Capt. Shere in closing his summary letter of November 8: “The opinion of the preparing officer is that this object may possibly have been an unidentified aircraft, possibly confused by the runways at Kirtland AFB. The reasons for this opinion are: (a) The observers are considered competent and reliable sources, and in the opinion of this interviewer actually saw an object they could not identify. (b) The object was tracked on a radar scope by a competent operator. (c) The object does not meet identification criteria for any other phenomena.”

The stunning non sequitur of that final conclusion might serve as an epitome of 22 years of Air Force response to unexplainable objects in our airspace. But when one then turns to the Condon Report’s analysis and evaluation, a Report that was identified to the public and the scientific community as the definitive study of UFOs, no visible improvement is found. Ignoring almost everything of interest in the case-file except that a lighted airborne object came down near Kirtland airfield and left, the Condon Report covers this whole intriguing case in two short paragraphs, cites the Air Force view, embellishes it a bit by speaking of the lost aircraft as “powerful” (presumably to account for its observed Mach 1 climb-out) and suggesting that it was “flying without flight plan” (this explains why it was wandering across runways and taxiways at night, in a rain, at an altitude of a few tens of feet), and the Report then closes off the case with a terse conclusion: “There seems to be no reason to doubt the accuracy of this analysis.

Two telephone calls to the two principal witnesses would have confronted the Colorado investigators with emphatic testimony, supporting the contents (though not the conclusions) of the Bluebook file, and that would have rendered the suggested “powerful private aircraft” explanation untenable. By not contacting the witnesses and by overlooking most of the salient features of the reported observations, this UFO report has been left safely in the “explained” category where Bluebook put it. One has here a sample of the low scientific level of investigative and evaluative work that will be so apparent to any who take the trouble to study carefully and thoroughly the Condon Report on UFOs. AAAS members are urged to study it carefully for themselves and to decide whether it would be scientifically advisable to accept it as the final word on the 22-year-long puzzle of the UFO problem. I submit that it is most inadvisable.
