The nations of the world will have to unite, for the next war will be an interplanetary war. The nations of the earth must someday make a common front against attack by people from other planets.
General Douglas MacArthur
I believe that these extra-terrestrial vehicles and their crews are visiting this planet from other planets. Most astronauts were reluctant to discuss UFOs. I did have occasion in 1951 to have two days of observation of many flights of them, of different sizes, flying in fighter formation, generally from east to west over Europe.
Gordon Cooper
Of course the flying saucers are real, and they are interplanetary.
Air Chief Marshall Lord Dowding
Head of Royal Air Force during World War II
It is my thesis that flying saucers are real and that they are space ships from another solar system. There is no doubt in my mind that these objects are interplanetary craft of some sort. I and my colleagues are confident that they do not originate in our solar system.
Dr. Herman Oberth
Father of modern rockerty
Unknown objects are operating under intelligent control. It is imperative that we learn where UFOs come from and what their purpose is. I can tell you, behind the scenes, high ranking military officers are soberly concerned about the UFOs.
Admiral Roscoe Hillenkoetter
Former Director of the C.I.A.
All Apollo and Gemini flights were followed, both at a distance and sometimes also quite closely, by space vehicles of extraterrestrial origin - flying saucers, or UFOs, if you want to call them by that name. Every time it occurred, the astronauts informed Mission Control, who then ordered absolute silence.
Maurice Chatelain
Former chief of NASA Communications Systems.
At no time, when the astronauts were in space were they alone: there was a constant surveillance by UFOs.
