Mainstream newspapers, popular magazines, technical journals, and declassified papers reported the existence of the gravity control propulsion research. For example, the title of the March 1956 Aero Digest article about the intensified interest was "Anti-gravity Booming." A. V. Cleaver made the following statement about the programs in his article:
Anti-gravity (also known as non-gravitational field) is the phenomenon of creating a place or object that is free from the force of gravity. It does not refer to either the lack of weight under gravity experienced in free fall or orbit , or to balancing the force of gravity with some other force, such as electromagnetism or aerodynamic lift .

Thomas Townsend Brown (March 18, 1905 – October 27, 1985) [1] was an American inventor whose research into odd electrical effects led him to believe he had discovered a type of anti-gravity caused by strong electric fields.
There have been follow-ups on the claims that this force can be produced in a full vacuum, meaning it is an unknown anti-gravity force, and not just the more well known ion wind. As part of a study in 1990, U.S. Air Force researcher R. L. Talley conducted a test on a Biefeld–Brown-style capacitor to replicate the effect in a vacuum. [11]
Wu's theory approximated the relative gravity loss as 0.03% (an order of magnitude smaller than the reported range of 0.3–0.5%). [ citation needed ] C. S. Unnikrishan, Tata Institute of Fundamental Research , Mumbai, showed that if the effect had been caused by gravitational shielding, the shape of the shielded region would be similar to a ...
As a motivation, seven examples of hypothetical space drives were described at the onset of the project. [1] These included the gravity-based pitch drive, bias drive, disjunction drive and diametric drive; the Alcubierre drive; and the vacuum energy based differential sail. [13] The project then considered the mechanisms behind these drives.
Since 2011, White had a team at NASA known as the Advanced Propulsion Physics Laboratory, or Eagleworks Laboratories, devoted to studying exotic propulsion concepts. [79] The group investigated ideas for a wide range of untested and fringe proposals , including Alcubierre drives , drives that interact with the quantum vacuum , and RF resonant ...
