This is the desert east of Palmdale, California, center of the US high-tech aerospace industry. From the scruffy landscape rise sheer metal buildings housing secret aircraft. To the north is Edwards Air Force Base and nearby, Air Force Plant 42, where Northrop hatched the B-2 bomber. A few hundred yards away is Lockheed Skunk Works, birthplace of the F-117 stealth fighter. But now I'm driving past old ranches with corrals jury-rigged from wire and discarded doors, beneath a sky as wide as the plain, looking for a very different kind of airplane.
