Additional Details ------------------------------ Product description: "This is a book about unidentified flying objects--UFOs--'flying saucers.' It is actually more than a book; it is a report because it is the first time that anyone, either military or civilian, has brought together in one document all the facts about this fascinating subject. With the exception of the style, this report is written exactly the way I would have written it had I been officially asked to do so while I was chief of the Air Force's project for investigating UFO reports--Project Blue Book."Foreword1 Project Blue Book and the UFO Story 2 The Era of Confusion Begins 3 The Classics 4 Green Fireballs, Project Twinkle, Little Lights, and Grudge 5 The Dark Ages 6 The Presses Roll--The Air Force Shrugs 7 The Pentagon Rumbles 8 The Lubbock Lights, Unabridged 9 The New Project Grudge 10 Project Blue Book and the Big Build-Up 11 The Big Flap 12 The Washington Merry-Go-Round 13 Hoax or Horror? 14 Digesting the Data 15 The Radiation Story 16 The Hierarchy Ponders 17 What Are UFO's? 18 And They're Still Flying 19 Off They Go into the Wild Blue Yonder 20 Do They or Don't They?
