Their personal testimonies provide a unique impression not just of the work that was carried out, but of the site itself. We reveal just how tight security had to be to keep the development of the U2, A12, HAVE BLUE and F117 Nighthawk aviation programs under wraps. This is a film that concentrates on delivering history and factual accuracy in a fresh and engaging style – one that answers the question of what really happened at Area 51.
