UFO and conspiracy books are a particularly guilty pleasure of mine. I believe nothing, but am entertained and thrilled by all of it. Jacobsen didn't fail me in this regard. She has piled up a fast, heated history of Area 51 and the elements of the "Military-Industrial Complex" which bred the secret base (and its matching mystery installations around the world and country). Much related here must be true, and most of it is quite reasonable and revelatory (stolen technologies, blundering atom bomb and h-bomb testing, and the grand architecture of great secrets). Jacobsen shows that everything is connected in this vicious and weird world of clandestine Nazi technology, spy planes, satellites, and radiation of all types. However, the knot in which she ties this squirming bundle of secrets with one more version of the Roswell Crash is unconvincing and arrived at with far less authority than any other part of the book.
