Retired Naval engineer Bill Tompkins, the author of Selected by Extraterrestrials, believes he was targeted by one group of ETs to be their representative back in the 1940s.
He told Linda Moulton Howe that while working for Naval intelligence during that period, he became aware of UFO program, and that a group of Reptilian aliens were giving Germany, space vehicles with anti-gravitational propulsion, as well as access to underground caverns in Antarctica where they could develop the new technology.
He also contended that when the first astronauts landed on the moon, Reptilians were standing on the surface underneath their vehicles, just out of camera range.
