Area 51 in the U.S. State of Nevada - also referred to as Dreamland or Groom Lake - is the most secret military test facility in the world. Insiders claim that even recovered spacecraft of extraterrestrial origin are studied and test flown here. In a three-year investigation, a German film crew dove deeply into the secrets of Dreamland, interviewing top scientists and security personnel who worked inside Area 51 and claim to have seen the recovered discs. This program includes film footage of the remarkable maneuvers of these mysterious craft secretly recorded during test flights.
