La possibile spiegazione di questo problema da parte di un grande ricercatore del passato:
If I were writing a book on, say, the Civil War, I would go to these
very same sources-old newspapers, historical records, letters of the
actual participants-and I would produce a book that would be accepted
by scholars and historians with little or no questions asked. But flying
saucers have been dragged down by the amateur theorists and thrown into
disrepute by the believers in extraterrestrial visitants. Their efforts have
produced skeptics who have found the obvious flaws in the beliefs and
have therefore decided that all UFO data are equally invalid.
