Information on UFOs, including sighting reports, has been and is still being officially withheld.

Government is afraid that people may think the worst and panic about these creepy horrible invaders. So the idea is: We have to avoid panic by all means.

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

I have the normal desire, experienced by everybody who's ever flown an airplane with a certain amount of zoom capability, to go a little bit higher and a little bit faster.

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.

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.

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.
