In this five-hour show, space technology consultant David Adair shared an incredible story of how in 1971, he was taken to a hangar at Area 51 to see an alien spacecraft (Adair, at the time, a teenager, was considered a rocket prodigy). He said he examined a gigantic engine in the shape of a number eight, covered with cascading fiber tubes like an enormous brain. He was asked to evaluate the object (which had a damaged core), based on work he had done with his own advanced rocketry.
