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.
Gordon CooperFor 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
Gordon CooperWhile 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 CooperWhile 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.
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 CooperA saucer flew right over (us), put down three landing gears, and landed out on the dry lakebed. (The cameramen) went out there with their cameras toward the UFO.... I had chance to hold (the film) up to the window. Good close-up shots. There was no doubt in my mind that it was made someplace other than on this earth.
