This book is part of the "The UFO Files" series, based on my own, old favorite UFO books. It can be read individually or as part of the entire series.
UFO is a fascinating subject that you can study in depth and constantly learn more about. This interesting and fascinating book is based on The Report on Unidentified Flying Objects by Edward J. Ruppelt. 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.
