A scientist who apparently worked in some capacity for Lockheed Martin has claimed aliens on Earth are real and have made contact with Earth in a video posted shortly before his death. Boyd Bushman apparently drew on his own personal experiences to reveal that extraterrestrials were in Area 51. And in a bizarre interview he also claims anti-gravity is one of several technologies being hidden by the government. The controversial video was apparently made shortly before Mr Bushman died on 7 August 2014. He had several patents attributed to him that were assigned to Lockheed Martin, and he was apparently also a senior scientist at the company - although that claim is disputed. These patents include a magnetic drive, an light beam to find objects, a thermally energised electrical power source and a heat radiation detection system. Was Bushman delusional or telling the truth? Certainly, Bushman believed in what he was saying. As long ago as 2008 he passed a polygraph test, during which he claimed he had worked on antigravity projects, alien technologies and had even met and photographed an alien, and examined at least eight different types of alien spacecraft. Bushman also revealed that he had received death threats and that security personnel had attempted to discredit him and tried to keep him from talking to the public.
