My favorite section in that book is when the Skunk Works guys trucked their stealth fighter prototype out to Edwards AFB for radar cross section testing. They stuck it up on a pole and then the AF guys in a radar van lit it up. And they could see it on radar just fine, and the Lockheed engineers were mystified, and the AF guys were giving them a hard time... until the vulture that had been perched on the prototype flew away and left nothing behind.
