Let us come to the point now. It would be nice to hold on to the common belief that the UFOs are craft from a superior space-civilization, because this is a hypothesis science fiction has made widely acceptable, and because we are not altogether unprepared, scientifically and even, perhaps, militarily, to deal with such visitors. Unfortunately, however, the theory that flying saucers are material objects from outer space manned by a race originating on some other planet is not a complete answer.
