For more than 50 years, people have reported seeing strange lights and strange aircraft around Area 51, the most mysterious military base in the United States.
Located on a stretch of desert near Groom Lake, Nev., Area 51 is the unofficial nickname for the base on the Nevada Test and Training Range operated by the U.S. Air Force.
The base and the sky over it are heavily guarded. But BL takes you inside for a look at some of the aircraft that have been tested at Area 51.
Take a look at the slideshow and then check out the January 2010 issue of Boys’ Life magazine for more information about these aircraft.
