"We all know that UFOs are real. All we need to ask is where do they come from."

— Captain Edgar D. Mitchell, Apollo 14 Astronaut, 1971.

"What does all this stuff about flying saucers amount to? What can it mean? What is the truth?" — Sir Winston Churchill - July 1952

"After I give lectures - on almost any subject - I am often asked, "Do you believe in UFOs?". I'm always struck by how the question is phrased, the suggestion that this is a matter of belief and not evidence. I'm almost never asked, "How good is the evidence that UFOs are alien spaceships?"."

— Carl Sagan, 'The Demon Haunted World,' 1996.

"The phenomenon of UFOs does exist, and it must be treated seriously."

— Mikhail Gorbachev, 'Soviet Youth,' May 4, 1990.

"UFOs are as real as the airplanes that fly over your head. . . . I'm so concerned about what the consequences might be of starting an intergalactic war, that I just think I had to say something. . . . The secrecy involved in all matters pertaining to the Roswell incident was unparalleled. The classification was, from the outset, above top secret, so the vast majority of U.S. officials and politicians, let alone a mere allied minister of defence, were never in-the-loop."

— Paul Hellyer, Canada’s Defence Minister from 1963-67, speech at the University of Toronto, 25 September 2005.
