Area 52, The Secret Sister of Area 51

Some of the greatest and most secretive airplanes in history have been developed in the Nevada desert, most of them at the now-infamous base known as Area 51. It turns out Area 51 has a sister facility -- Area 52 -- and it's a place with secrets of its own. Area 52 isn't quite as secretive as Area 51. For one thing, you can at least find it on some maps. But it's off limits to most of us because of the classified work that goes on out there. The base has been bombed, blasted, poisoned, and nuked in the pursuit of cutting edge technology that probably can't be tested anywhere else.
