Because of the comparative rarity of this craft, a broad range of data is hard to come by, however a synopsis of the known information is as follows:
This UFO resembles a Chinese peasant’s large straw hat. And also has been described as a Sombrero.
Insufficient estimates of the conical hat craft have been made to suggest a range of sizes, but one was reliably estimated to be in the order of 200 metres in diameter.
Colour has almost always been reported as metallic silver, both dull and polished. Conical hat UFOs have been seen at times to vibrate heavily.
If the craft is moving slowly, the movement seems jerky or jittery. A fibrillation would probably be the best way to describe it.
Report 1
Location: USA.
Report placed with the USAF Filter Center in Trenton in the form of an affidavit.
Even at risk of being called hysterical, hallucinated or worse, I feel I must make record, on my oath as a woman, an American and a member of the human race, of the following: –
That I saw an airborne object which bore no resemblance to any airplane, helicopter, balloon ever made and flown by man, so far as I know.
That I saw the object at a distance of not more than 150 yards at about 2pm, first from a rear window and then from out in the back yard of our home on the road from Great Meadows to Hope, New Jersey. The weather was clear under a low overcast sky, and the position of the object hovering in the air below our house was such that I could see it – and hear it – with absolute certainty and with concentrated effort to remember every detail.
That my attention was first drawn to the object’s presence by our dogs barking in their pens behind the house, and by their looking upward at the object, as they and I continued to do so easily until the object departed. That the shape of the object closely resembled that of a huge derby hat with a rounded domelike crown 30 to 40 feet high and at least 50 feet in horizontal diameter above a slightly curled-up “brim” that extended outward for 12 or 15 feet from the bottom of the crown. The brim or bottom surface of the object appeared to be sealed over smoothly and completely in a gentle curve, with no holes or ports or windows or vents of any kind, of which I could see none anywhere else on the entire object.
That in the absence of any openings into it, I could see no beings, human or otherwise, inside the object who might be operating and riding in it, and no crew or passengers were visible on the object’s exterior during its visit. That the colour of the object, all over, was a uniform white, dull but clean, with no spots, stripes or other markings whatsoever. Its texture was apparently non-metallic but reminded me strongly of clay pipe. There was a moderate breeze, from the northeast I think, was blowing in which the object hovered quite stationary except for a gentle rocking motion, like a boat at anchor on water. As the object rocked and in the same cadence it made a slow growling or rumbling sound that rose and fell irregularly.
That beneath the object, extending vertically toward the ground, I seemed to see, and then not see, and then see again, a lot of streamers or lines of some material (or force) that twinkled like the fragile strands of tinsel with which one decorates a Christmas tree. That without any marked change of sound except a soft rush of air, sucking away and not blowing toward me, the object abruptly ascended almost vertically, slightly northeasterly at immense speed into thick cloud cover (maybe 300 feet up) and was instantly gone from sight and hearing.
Report 2
Location: Korea.
Three fighter bombers took off from the deck of a carrier of the coast of Korea on an early morning flight to bomb a truck convoy in the Yalu River valley. As the sun came up they were flying northward over the valley at 10,000 feet.
The lead pilot was startled to see two large shadows moving at high speed along the ground, coming from the northwest. He looked up and saw that two huge UFOs were causing the shadows. His radar showed that they were moving at a relative velocity of 1,000 to 1,200 mph when they suddenly stopped, assuming the velocity of the planes at a distance of a mile and a half.
They seemed to begin a jittering or fibrillation motion. The pilot’s reaction was to shoot. He readied his guns and gun cameras, but the radar went haywire. The screen bloomed, becoming very bright and he realized the radar had been jammed. He called the carrier, but each frequency that he tried was successively jammed by a buzzing, a moment after he turned it on. All the while the objects were jittering out ahead, maintaining the speed of the planes. The pilot used reference points on the windshield and the previously determined range to determine their size. They were between 600 and 700 feet in diameter.
They were shaped like conical hats with oblong ports in the crown, through which copper-green lights shone. The objects had a shiny, silvery appearance with a reddish glow surrounding them. Above the ports was a shimmering red ring, encircling the top portion. The bottom was black except near the periphery, which glowed red. The black part never jittered.
The objects then began maneuvering around the flight squadron, circling above and below. At this time all six men in the three planes experienced a feeling of warmth in the airplanes and a high-frequency vibration. After the flight, they found that all the gun camera film had been exposed or fogged, and that the luminous paint used on the instrument dials had become extremely bright; the paint had been rejuvenated.
Report 3
Location USA.
Awoken by the frenzied barking of their dog, a migrant family heard a noise like a big swarm of wasps. Going outside their caravan they saw a twenty-five to thirty metre “sombrero hat” shape giving off a violet glow. Three “men” descended in a tiny craft similar in shape to the large one. These men seemed to be three times the size of a normal human being.
They gave off a violet-yellowish glow, as they collected plants and sugar cane which were sucked up into the large craft via a transparent tube. After ten minutes the men re-entered their ship which took off. As it did so the hair on the family’s heads and arms stood up.
