Dr. Paul LaViolette, discussed the physics behind anti-gravity propulsion technology and showed how it is not only possible, but is currently being used in secret projects by our own government. "We're sort of being held in a 'technology cage,' on purpose, for fear of change," he said about what he believes to be a decades-long clandestine development of anti-gravity technology by the United States. "A lot of this work has been going on since the end of WWII, if not before," LaViolette said about the quest to break the bonds of gravity. He detailed some of the early experiments conducted by Nikola Tesla and T. Townsend Brown, who both used electricity to affect gravity. LaViolette noted that, in the mid-1950's, numerous aviation companies were not only attempting to develop anti-gravity technology but were quite open and enthusiastic about it -- until 1959. "Suddenly it was like a blackout in the media," he observed. This sudden silence, LaViolette surmised, was at the behest of the US government. He asserted that the B2 Stealth Bomber is a contemporary craft that utilizes anti-gravity capabilities. LaViolette speculated that it uses jet engines to take off, but then makes use of anti-gravity propulsion to maneuver. This, he said, adds an additional layer to the jet's stealth capabilities since, if his theories were correct, it could "go into the stratosphere, or beyond, and then just come down directly over the country they were entering."
