I know other astronauts share my feelings.... And we know the government is sitting on hard evidence of UFOs.

Intelligent beings from other planets regularly visit our world in an effort to enter into contact with us. NASA and the American government know this and possess a great deal of evidence. Nevertheless, they remain silent in order not to alarm people. I am dedicated to forcing the authorities to end their silence.

I believe that these extra-terrestrial vehicles and their crews are visiting this planet from other planets, which obviously are a little more technically advanced than we are here on earth.

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 did have an occasion in 1951 to have two days of observation of many flights of them, they were of different sizes, flying in fighter formation, generally from east to west over Europe.

While flying with several other USAF pilots over Germany in 1957, we sighted numerous radiant flying discs above us. We couldn't tell how high they were. We couldn't get anywhere near their altitude.

Several days in a row we sighted groups of metallic, saucer-shaped vehicles at great altitudes over the base Germany, 1951 and we tried to get close to them, but they were able to change direction faster than our fighters. I do believe UFOs exist and that the truly unexplained ones are from some other technically advanced civilization.
