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.
Gordon CooperI 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.
Gordon CooperSeveral 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.
