The 1950s Antigravity Programs That Vanished as Aerospace Companies Claimed a Breakthrough
In the 1950s, major aerospace companies publicly predicted that gravity-defying propulsion was close. Then the subject disappeared.
This reel examines George Trimble’s G-Project at Martin Aircraft, the sudden silence surrounding antigravity research and the theory that a breakthrough may have moved into classified programs—just as nuclear fission went dark before the Manhattan Project.
