Summary
This 1950 CIA information report from Chile summarizes a German scientist's article proposing that 'flying discs' could be a new type of aircraft based on aerodynamic research conducted in Germany around World War I. The theory suggested such craft might use rotating cylinders or gas turbines to generate lift through boundary-layer manipulation rather than conventional wings.
Detail
Released through the PURSUE declassification, this 1950 CIA Information Report originating from Chile discusses an article written by a German scientist about the nature of 'flying discs.' The article theorized that such objects could be explained as a new type of aircraft built on aerodynamic principles developed at German research facilities during and after the First World War.
According to the report, the proposed design would use rotating cylinders or gas turbines to create lift through manipulation of the boundary layer, rather than relying on conventional wings. A redacted version of this report has previously been available on the CIA's public website.
