All you need is a “credible” witness who has had an experience, and then you dare someone else — like the government — to “prove it DIDN’T happen.” Unfortunately, this sort of mindset permeates UFOlogy culture, making it very difficult to get a straight story. … It is not any weight of empirical evidence, rather a proliferation of “let me tell you what I saw” experiences. This does not deny that these experiences may have actually occurred, but we’ve all heard fishing stories… Add to this normal human failing a potentially spectacular UFO claim, with eager media and UFOlogists beating down your door, and often the truth is lost along the way — either in the recounting by the witness or the telling of the tale by the media. This gives you some idea of how difficult the process of determining the truth can be. But, nonetheless, we shall try to determine the true nature of the phenomenon.
