Throughout the 1950s and 1960s, while publicly dismissing the existence of UFOs, the United States Air Force was engaged in a secret programme of evaluating every report of unidentified flying objects. Under the code name, Project Blue Book, the Air Force analysed over 13,000 incidents. The goal of this enterprise was threefold: To determine the cause for each UFO sighting, to assess the security threat for each incident and to determine how the United States could obtain or create the technology used by UFOs. This book, based on secret files obtained through the Freedom of Information Act, includes accounts of seven of the most important USAF enquiries - among them the story of the nights the White House was buzzed by UFOs, the mystery of the Lubbock Lights, the full story of Captain Mantell - Ufology's first martyr and the startling conversion of the prominent astronomer, J. Alan Hynek from UFO sceptic to believer. This is startling and fascinating book that uncovers, not only the anatomy of a government cover-up, but, also, provides stark and chilling evidence that we are not alone. It is all here - government documents, the testimony of scientists, the military, pilots and citizens all over the USA who have witnessed UFOS. PROJECT BLUE BOOK refers to the following: 1. The name of new History Channel series based on the true, top-secret investigations into UFOs and related phenomena conducted by the United States Air Force from 1952 to 1969 with Dr. J. Allen Haynek playing a central role. 2. The name of the original government study and subsequent report. 3. The title of the book edited by Brad Steiger and originally published by Ballantine in 1976 containing details from the government report.
