Query: WORTH A READ FOR UFO FANS

The (brilliant) illustrations and the (weird) technology described by the authors seems "sci-fi" to us, even now in the XXI century, and most of the times this book is closer to UFO literature than to military themes. But that's what makes the book BIG fun to read. So if you are interested in secret technology, nazi conspiracy and UFO stuff... you must read this book.
