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 spyplane, due to its remoteness, 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.[1]

Bob LazarEdit

In 1989, Bob Lazar claimed on a Las Vegas television station, that he had worked with alien spacecraft at Papoose Lake, south of Area 51. Since then, "Area 51" has become a popular symbol for the alleged U.S. Government UFO cover-up.[1]


Area 51 begins its underground base expansion as a Deep Underground Military Base (D.U.M.B) starting in 1972 as a two-year project (Lear, 1987). Further underground expansion from Groom Lake toward the Tonopah Test Range is conducted in 1985/6 (Lear, 2018).
