Operation Paperclip brought WWII-era German rocket scientists over to the US to participate in the space program. If this book is to be believed, these scientists were valued not only for their expertise with rocketry, but with other more exotic technologies as well, including antigravity. If antigravity research WAS going on in wartime Germany, it didn't produce any weapons to help them win them the war, but apparently it showed promise. Since hard evidence of antigravity research is lacking, one has to wonder if the whole story was just a ruse... maybe something to bargain with during the surrender. That's not unreasonable, considering some German rocket scientists apparently DID finesse their way out of standing trial at Nurenburg by hinting that they had knowledge of this antigravity technology. So is there anything to the myth of antigravity? It's hard to say. Something like that would be highly classified. The author tries to draw connections between the nascent technology and UFO sightings. The reader is left to decide how much to believe.Chillingly, it looks like several German scientists may have lost their lives because of the myth (or reality) of antigravity technology. Even if antigravity technology doesn't exist, that story alone makes this a gripping book.
