Person

Gordon Cooper

Mercury and Gemini astronaut (Mercury 9, 1963; Gemini 5, 1965) and U.S. Air Force test pilot. He said that as a fighter pilot in West Germany in 1951 he chased formations of discs, and that at Edwards AFB in 1957 a crew filmed a saucer landing that he sent up the chain. He wrote to the United Nations in 1978 urging a UFO study, and spoke of UFOs publicly until his death in 2004.

Witness profile

Mercury and Gemini astronaut and Air Force test pilot who said he chased disc formations over West Germany in 1951 and saw a 1957 Edwards landing film go to Washington. In his own debriefs he is careful: one sighting from orbit 'may or may not have been a satellite'.
