One night in May 1989, a reporter broadcast a story from a satellite link in Las Vegas, Nevada. A young physicist spoke under hidden identity, and told us of nine alien discs held near Groom Lake by a small autonomous group of the American government. He used the pseudonym "Dennis," which turned out to be the name of his superior at the base. A few weeks later he went on camera using his real name, Bob Lazar, and he has been the subject of worldwide curiosity, speculation and controversy ever since.
