Erich A. Aggen, Jr., in his article ‘TOP SECRET: ALIEN UFO BASES’ (SEARCH Magazine, Summer 1991 issue), presented the following revelations concerning the UFO-Subterranea connection:

“…A great deal of UFO research has also led to the conclusion that various…species of aliens have set up secret underground bases in the United States and other countries. It is logical to assume that such bases have also been established elsewhere in the solar system. If such bases exist, where would we find them? Existing information allows us to make a few educated guesses.

“EARTH BASES: UNDERGROUND – The dark, cavernous world beneath out feet is the source of many baffling mysteries. Clandestine UFO bases may be hidden deep within the earth in natural and/or artificial caverns. As a former member of the National Speleological Society (NSS), I am well aware of the vast extent of cave systems within the United States. In my own native state of Missouri, for example, there are over 2,500 known caves and dozens of new ones being discovered every year. Many of these caves are intricately linked together by numerous passageways and interconnecting chambers.

“One particular species of blind white (albino) cave fish, the TYPHLICHTHYS, has been found in many widely separated cave systems over several states. It has been found in caves that make a great arc through Kentucky, Indiana, Illinois and UNDER the Mississippi River extending into Missouri, Arkansas, and Oklahoma! A VAST SECTION OF THE CENTRAL AND SOUTHERN UNITED STATES MUST LIE ABOVE ONE IMMENSE CAVERN SYSTEM!

“Many caves possess rooms hundreds of feet in length, width, and height. In most cases, these huge natural caverns can only be reached and explored with the utmost skill and perseverance. There are only a few thousand NSS members in the United States and only a few hundred of this number are active spelunkers. With so few spelunkers spread over such a large area, only a very small fraction of the tens of thousands of known caves in this country have been carefully mapped and explored. Thousands of other caves remain undiscovered and unexplored.

“Extensive evidence indicates that caves in the United States may be connected with caves in other parts of the world. In Mexico, the cave known as ‘Sotano de las Golondrinas’, (or) basement of the swallows, in the Municipio de Aquismo, S.L.P., reaches a depth of 1100 feet (334 meters). The cave is actually a giant ‘sinkhole’ or ‘hole’ in the ground with a nearly circular opening at the top, hundreds of feet in diameter. It is impossible to climb down the sides of Golondrinas because the walls of the opening are too smooth and “belled-out”. To reach the bottom of the cave, a special rope over 1100 feet long must be secured at the top of the opening and dropped into the sinkhole. Explorers must then descend into the yawning hole one at a time using special cave repelling gear and climbing techniques. At the bottom of Sotano de las Golondrinas are numerous ‘leads’ or openings to a multiplicity of different crevices, passages, crawlways, and rooms which have never been mapped or investigated.

“The entrance to Golondrinas is located in one of the most primitive and uncivilized areas of Mexico and local inhabitants are afraid to approach the cave because they believe it is full of ‘evil spirits’ which lure people to their deaths. They tell stories of people mysteriously disappearing never to be heard from again while passing near the cave entrance. These stories may be based more on fact than fiction: they are similar in some respects to UFO abduction reports. Because of its huge size, remote location, and unique geological structure, Golondrinas would be an ideal UFO base. Naturally camouflaged caves in other parts of the world may serve as excellent natural bases, way stations, and ‘depots’ for UFOs.

“An underground nuclear test called the ‘Schooner Experiment’ conducted in December, 1968, substantiates the theory that caves in North and South America are intimately linked. In this test, a 35- kiloton nuclear bomb was exploded under the desert of Nevada. Five days after the test, the radiation level rose from 10 to 20 times in Canada, 1000 miles away from the Nevada test site! The only way the radioactive dust could have traveled that far is through an interconnected system of caves extending all the way from Nevada to Canada!”
