Bad UFOs: Critical Thinking About UFO Claims

“What explains the human fascination with UFOs? The first reported sighting of what was then called “flying saucers” was by private pilot Kenneth Arnold on June 24, 1947. Within a few weeks, an entire “wave” of saucer sightings swept across the U.S., and soon across the world. And within a few years this had expanded to give us UFO crashes, the Men In Black, UFO bases, military and intelligence agency conspiracies, NASA conspiracies, alien abductions, crop circles, alien autopsies, alien-human hybrids, cattle mutilations, and the list just continues to grow.

“Do the “saucers” (later renamed “UFOs”) represent visitors from some other planet, or possibly even something more bizarre? How have they evaded unambiguous detection for about seventy years? Is this because the methods of science cannot capture them? Or do reports of UFOs have much in common with reports of ghosts, witches, Bigfoot, and other creatures that are widely discussed and widely believed, but exist only in the imaginations of those who pursue them?”

UFO Sightings: The Evidence

Written from the skeptical perspective, and applying the scientific method to the cases explored, this book differs greatly from the proparanormal tomes widely available today.”

Review by Ronald A. Schorn in Sky and Telescope Magazine (Nov. 1981):

“The author has produced a useful, informative, interesting, and well-written work. … The UFO “movement” has had a long, complex, raucous history, and the author threads his way neatly through the tangle of acronyms that litter the organizational UFO scene. … All in all, Sheaffer sees UFOlogy as a powerful social movement which, fundamentally, is a reaction against science and reason. He blends this view with specific cases and general background in this dandy work, always providing references so the reader can check up on him. If you’re only going to have one book on UFO’s, this is the one….”
