A complete investigation of the development and suppression of antigravity and field propulsion technologies• Reveals advanced aerospace technologies capable of controlling gravity that could revolutionize air travel and energy production• Reviews numerous field propulsion devices that have thrust-to-power ratios thousands of times greater than a jet engine• Shows how NASA participates in a cover-up to block adoption of advanced technologies under military developmentIn Secrets of Antigravity Propulsion, physicist Paul LaViolette reveals the secret history of antigravity experimentation–from Nikola Tesla and T. Townsend Brown to the B-2 Advanced Technology Bomber. He discloses the existence of advanced gravity-control technologies, under secret military development for decades, that could revolutionize air travel and energy production. Included among the secret projects he reveals is the research of Project Skyvault to develop an aerospace propulsion system using intense beams of microwave energy similar to that used by the strange crafts seen flying over Area 51.
