Anti-gravity

Anti-gravity is a hypothetical means of countering or otherwise modifying the effects of gravity, typically in the context of spacecraft propulsion. Such systems are limited to the realm of science fiction given the current understanding of the way gravity works, but this has not stopped legions of hopefuls from making various spinning disks and magnets in hopes of perfecting such a device.

The United States government and aerospace contractors publicly announced ambitious Manhattan project-style goals to crack the anti-gravity problem during the mid-1950s while the atomic airplane was on the drawing board, but by the end of 1957 no more information was flowing into the newspapers and magazines. Either their work never produced anything, or the projects were taken into the world of top secret.
