Emenegger said that the landing took place at 6 a.m. The alien visitors had eyes with a vertical slit, and their mouths were thin and slitlike, with no chins. He was promised by the USAF to get 3200 feet film of UFO landing but at the last moment, they refused to use it due to the “Watergate Scandal.” Despite it, Emenegger and Sandler were asked to describe the Holloman episode as something hypothetical, which might happen in the future.
After months of research and film production, Emenegger felt cheated as the permission of using real footage was withdrawn. Anyway, he released his Golden Globe-nominated documentary, “UFOs: Past, Present, and Future
” in 1974. It turned out to be groundbreaking due to the information provided by the DoD. The USAF forced Emenegger to add the animated footage of the alleged Holloman UFO landing.
As per Emenegger, the alleged real landing footage was not fully missing from the frames. He said some frames from the original footage were used in the reconstruction during the editing stage, which was authorized by the USAF. The viewers spotted a genuine bright disc coming down slowly in the distance against the backdrop of Holloman’s surrounding landscape.
