Thanks for clear thinking post on this. I was really impressed with the daughter of the man who was forced by the US Government to change his story on the early Area 51 era crash. She remembered as a middle aged adult her memory as a little girl being upset at one of the few times she saw her father cry. He was discussing how the government forced him to make up a cover lie story and say he never saw the UFO crash scene and it was aluminum foil made to look like alien metal and so on.
Others chose “nutjob loony who hallucinated seeing a flying saucer” and lost his career or “officer recanted and admits no one saw a ufo.”
Are you referring to the Roswell crash?
