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.

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.

While working with a camera crew supervising flight testing of advanced aircraft at Edward's Air Force Base, California, the camera crew filmed the landing of a strange disc object that flew in over their heads and landed on a dry lake nearby. A camera crewman approached the saucer, it rose up above the area and flew off at a speed faster than any known aircraft.

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

Father, we thank you, especially for letting me fly this flight - for the privilege of being able to be in this position, to be in this wondrous place, seeing all these many startling, wonderful things that you have created.

I live for that exhilarating moment when I'm in an airplane rushing down the runway and pull on the stick and feel lift under its wings. It's a magical feeling to climb toward the heavens, seeing objects and people on the ground grow smaller and more insignificant. You have left that world beneath you. You are inside the sky.

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