Donald Slayton a Mercury astronaut revealed in an interview he had seen UFOs in 1951:
“I was testing a P-51 fighter in Minneapolis when I spotted this object. I was at about 10,000 feet on a nice, bright, sunny afternoon. I thought the object was a kite, then I realized that no kite is gonna fly that high.”
As I got closer it looked like a weather balloon, gray and about three feet in diameter. But as soon as I got behind the darn thing it didn’t look like a balloon anymore. It looked like a saucer, a disk.
About the same time, I realized that it was suddenly going away from me — and there I was, running at about 300 miles per hour. I tracked it for a little way, and then all of a sudden the damn thing just took off. It pulled about a 45 degree climbing turn and accelerated and just flat disappeared.”
“For many years I have lived with a secret, in a secrecy imposed on all specialists in astronautics. I can now reveal that every day, in the USA, our radar instruments capture objects of form and composition unknown to us. And there are thousands of witness reports and a quantity of documents to prove this, but nobody wants to make them public.
Why? Because authority is afraid that people may think of God knows what kind of horrible invaders. So the password still is: We have to avoid panic by all means.”
“I was furthermore a witness to an extraordinary phenomenon, here on this planet Earth. It happened a few months ago in Florida. There I saw with my own eyes a defined area of ground being consumed by flames, with four indentations left by a flying object which had descended in the middle of a field. Beings had left the craft (there were other traces to prove this). They seemed to have studied topography, they had collected soil samples and, eventually, they returned to where they had come from, disappearing at enormous speed…I happen to know that authority did just about everything to keep this incident from the press and TV, in fear of a panicky reaction from the public.”
