"Unidentified Flying Objects"—exactly what are they? Are they interplanetary spaceships manned by intelligent beings? Or is the whole UFO business just a mass of hoaxes, hallucinations, and readily explained natural phenomena?

This is the first serious book about UFOs to be written by anyone actively connected with the official investigation of these phenomena. As chief of the Air Force project assigned to the investigation and analysis of UFOs, Mr. Ruppelt and his staff studied over 4,500 reports and discussed them with everyone from out-and-out crackpots to top-level scientists and generals.

All reports received were subjected to military intelligence analysis procedures. Astronomers, physicists, aerodynamic engineers, and psychologists were consulted in the course of the Air Force's exhaustive investigations.

The official Air Technical Intelligence Center reports of their findings, many details from which are revealed for the first time in this book, contain some completely baffling detailed accounts of UFO sightings by thoroughly reliable witnesses.

Here are the complete official accounts of the classic cases—the Lubbock Lights, the Utah Movies, the Florida Scoutmaster, the Washington Sightings—as well as a wealth of less-publicized but equally amazing incidents.

While others who have written books and articles on UFOs imply that they were conferring with officials in the inner sanctum, Mr. Ruppelt, as this fascinating book makes clear, was the inner sanctum.
