S1, E5: A mysterious, stark terrain, 90 miles north of Las Vegas, goes by many names: The Box, Paradise Ranch, Groom Lake, Watertown Strip, and Dreamland. But most refer to the region as Area 51. Since the late 1950s, an array of UFO sightings has been reported above its skies. In 1989, revelations of Las Vegas resident Bob Lazar brought Area 51 to national attention. Lazar claimed to possess amazing inside information, but he wasn't the first to state that something strange was going on. Those who discount Lazar's theories think the government kept its activities from the general public for a more plausible reason. The base, built at the Cold War's height, housed testing of cutting-edge aviation technology. The cloak of secrecy was to keep the Soviet Union in the dark, not the American public, and experts expostulate that the government perpetuated these theories to disguise its real activities.
