A twenty-year study of the previously classified files of the Air Force's UFO study, Project Blue Book, concludes that the U.S. military covered up evidence of extraterrestrial visitation of Earth from the American public. 20,000 first printing. IP.
Does an excellent job of highlighting how the Air Force was not interested in finding the truth of UFO cases, but was instead focused upon "explaining" away the reports regardless of whether the explanations were valid or even possible.
Here you get a brief history of Project Blue Book followed by all the major cases they investigated. From Kenneth Arnold's sightings to all the other twilight zone stories and the close encounter chase of 1966. What to make of all this? Find out by reading it yourself and form your opinion accordingly. The book comes with an outstanding appendix. Only missed some photo material in here otherwise it was pretty good and scary. Really recommended!
This is an excellent clear picture of the Project Blue book fraud. Kevin Randle goes into the details on what was and was not done in investigating these cases. The cases are logically presented and statements the author makes are backed up with and extensive bibliography and great addendums, so you can find the information too.
