Holloman Air Force Base[edit]
Clark cites a 1973 encounter as perhaps the earliest suggestion that the U.S. government was involved with ETs. That year, Robert Emenegger and Allan Sandler of Los Angeles, California were in contact with officials at Norton Air Force Base in order to make a documentary film. Emenegger and Sandler report that Air Force Officials (including Paul Shartle) suggested
incorporating UFO information in the documentary, including as its centerpiece genuine footage of a 1971 UFO landing at Holloman Air Force Base in New Mexico. Furthermore, says Emenegger, he was given a tour of Holloman AFB and was shown where officials conferred with Extraterrestrial Biological Entities (EBEs). This was supposedly not the first time the U.S. had met these aliens, as Emenegger reported that his U.S. military sources had "been monitoring signals from an alien group with which they were unfamiliar, and did their ET guests know anything about them? The ETs said no" (Clark 1998, 144).[22]
The documentary was released in 1974 as UFO's: Past, Present and Future (narrated by Rod Serling) containing only a few seconds of the Holloman UFO footage, the remainder of the landing depicted with illustrations and re-enactments.
In 1988, Shartle said that the film in question was genuine, and that he had seen it several times.
In 1976 a televised documentary report UFOS: It Has Begun[35] written by Robert Emenegger was presented by Rod Serling, Burgess Meredith and José Ferrer. Some sequences were recreated based upon the statements of eyewitness observers, together with the findings and conclusions of governmental civil and military investigations. The documentary uses a hypothetical UFO landing at Holloman AFB as a backdrop.
