Query: Breakthrough book on the Tesla-UFO connection

Lyne's book is THE most important book published to date on the origin of "saucers" as man-made craft using stolen Tesla technology. Although Pentagon Aliens and its author are seldom mentioned by others, they have had a major impact on the UFO field. In fact, I believe all other UFO books need to be compared to Lyne's Pentagon Aliens to see whether they can hold up to Lyne's information on Tesla, ether propulsion and military disinformation.Previous reviewers mention 2 weak points of the book, namely a strong pro-atheist position and a circuitous writing style. In fact that is why I gave the book 4 stars instead of 5. But come on, no book is perfect. Think of Pentagon Aliens as a gold mine and you'll have to do some digging to find the many great nuggets of information throughout its pages. For example, his expose on the military's ad hoc Roswell hoax alone is worth the price of the book.
