This is a book about unidentified flying objects: UFOs - 'flying saucers.' It is actually more than a book; it is a report because it is the first time that anyone, either military or civilian, has brought together in one document. But more often than not these facts have been obscured by secrecy and confusion, a situation that has led to wild speculation on one end of the scale and an almost dangerously blase attitude on the other. It is only when all of the facts are laid out that a correct evaluation can be made. The report was difficult to write because it involves something that doesn't officially exist. It is well known that ever since the first flying saucer was reported in June 1947 the Air Force has officially said that there is no proof that such a thing as an interplanetary spaceship exists. But what is not well known is that this conclusion is far from being unanimous among the military and their scientific advisers because of the one word, proof; so the UFO investigations continue. The hassle over the word 'proof' boils down to one question: What constitutes proof? Does a UFO have to land at the River Entrance to the Pentagon, near the Joint Chiefs of Staff offices? Or is it proof when a ground radar station detects a UFO, sends a jet to intercept it, the jet pilot sees it, and locks on with his radar, only to have the UFO streak away at a phenomenal speed? Is it proof when a jet pilot fires at a UFO and sticks to his story even under the threat of court-martial? Does this constitute proof? The at times hotly debated answer to this question may be the answer to the question, 'Do the UFO's really exist?' I'll give you the facts - all of the facts - you decide!
