Whereas there is surely a mountain of material on secret (or 'secret') Nazi technology, this is surely not the book to read about it. When you read such a book the most important thing is: SOURCES. As it is, the author's notable sources include:
-an article in some french magazine from the 60's, author unknown -someone who called the author late one night and told him that a cousin of his witnessed something back in the war -a passage from Iron Coffins (great book on u-boats) where a u-boat captain is sick of hearing about secret weapons and says so. In the author's train of thought, because u-boat captains were the elite, they also had access to intel about the latest gadgets and weaponry (of course!!!), therefore his mentioning some secret weapon means THEY'RE REAL! RUN FOR YOUR LIVES!
It is very interesting. The early chapter move along quickly. There is enough information, to get you headed in a direction. There is so much information about different technologies, or possible technologies, that this is just enough information, to send you looking for more if you so wish.
Surprisingly clearly well written for a conspiracy book. Basically, the author limits to enumerate a series of possibly German-developed technology based on de-classified US reports, never elaborating too much on each case (the purpose of the book is to provide hints for further investigation). In being eager to provide proofs of the German advancement in many fields, the author contradicts himself, as the case of a nuclear test reportedly witnessed by an Italian government member in 44, on the Ruegen Island, whereas on another report he mentions since Germany was not very advanced in nuclear technology in 44, it decided to explore other alternatives.
