2019 Reprint of 1956 Edition. Full facsimile of the original edition, not reproduced with Optical Recognition software. This was 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 4500 reports and discussed them with everyone from out and out crackpots to top level scientists and generals. 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.
