Report published in December 1956 by Aviation Studies (International) Ltd of London, the companion volume to Electrogravitics Systems Report 1956 of February the same year, and the second of the two documents the London intelligence service sold to the aerospace industry on the state of gravity research.
What the pair establishes
Together they are the documentary core of the 1956 Antigravity Press Window: that between roughly 1955 and 1957 a commercial intelligence service considered gravity control a subject worth two paid reports, and that named executives at named companies discussed it publicly in the same period. That is a fact about the industry’s attitude, and it is checkable. It is not a fact about physics.
Its condition
Both reports became difficult to obtain, which is itself part of the argument in The Hunt for Zero Point: Nick Cook traces the only surviving American copy of the February report to the technical library at Wright-Patterson Air Force Base, and the Aviation Studies volumes had gone from the Library of Congress. Scarcity is not evidence of suppression on its own, since privately published industry reports of the 1950s are routinely hard to find, and both are now in circulation.
