Thomas Townsend Brown
An American physicist who became controversial over his work on gravity control because the propulsion method was just like the theory of how a flying saucer worked. He allegedly became involved with what came to be known as The Philadelphia Experiment along with Nikola Tesla and Albert Einstein. He was perhaps the John Hutchison of his day who has demonstrated levitation, if not gravity control, and has documented it on video. Townsend Brown died in the 80's still carrying out gravity control experiments and it is said he died of ozone poisoning.
Gravity Control is a matter of time.
Anti-gravity technology research in electromagnetic propulsion and other technologies is under development, and we would like to document its discovery.
