The mystery base known as Area 51
This article is on Area 51. You won't be vacationing here anytime soon, but lets take a look into this mysterious location:
Area 51, also known as Groom Lake, is a secret military facility about 90 miles north of Las Vegas. The number refers to a 6-by-10-mile block of land, at the center of which is a large air base the government will not discuss. The site was selected in the mid-1950s for testing of the U-2 spy plane, due to its remoteness and proximity to existing facilities and presence of a dry lake bed for landings.
Groom Lake is America's traditional testing ground for "black budget" aircraft before they are publicly acknowledged. The facility and surrounding areas are also associated -- with varying levels of credibility -- with UFO and conspiracy stories. Someday, we will find out all the secret stuff!
