From the source: Release of 2026-06-12 This 1950 CIA Information Report from Chile discusses a German scientist's article theorizing that "Flying Discs" could be explained as a new type of aircraft based on aerodynamic principles developed in German research facilities during and after WWI, using rotating cylinders or gas-turbines to create lift through boundary layer manipulation, rather than conventional wings. A redacted version of this report has been available on CIA's public website.

The article is entitled "The Mystery of the 'Flying Discs,' a contribution to its possible explanation". The significant conclusion drawn by this scientist in this report is that the old handscap of "boundary layer" or a moving object or airfoil has been exploited to produce an advantageous reaction and is the factor controlling the success of the "flying saucer" type of airfoil.
