Flying saucers from outer space.

"Three years ago, in a book entitled 'The flying saucers are real', I reported the results of my first investigation into this world-wide mystery. At that time I stated my belief that the U.S. Air Force knew the answer and was hiding it from the public. Since July 1952, in a new investigation of the saucers, I have been privileged to co-operate with the U.S. Air Force. Because of my present understanding of their very serious problem, and certain dangers inherent in the situation, I have been given information unknown to most Americans... It is my hope that this book will help prepare everyone, whether sceptics or believers, for the final act of the saucer drama"--Foreward by Donald E. Keyhole, page 11.
