The Mystery of the 'Flying Discs': A contribution to its possible explanation

This Central Intelligence Agency Information Report, dated July 31, 1950, transmits a translated article by Dr. Eduard Ludvig, originally published in the German-language magazine 'Condor' in Chile. The report addresses the phenomenon of 'flying discs' or 'flying saucers,' which the author argues should be approached with skepticism regarding their mysterious nature. Dr. Ludvig, who claims to have worked in the research plant of Professor Junkers in Dessau, posits that these objects are not extraterrestrial but are instead the product of advanced German aeronautical science. He details the history of aerodynamic research, specifically referencing the 'Kutta-Jukovski Theory of Airplane-wingbeam' and the concept of the 'boundary layer.' Ludvig explains that the 'flying disc' phenomenon can be theoretically explained by the exploitation of this boundary layer to produce lift, a concept he links to the 'Flettner-Rotor' and the use of gas-turbines. He notes that during his time in Germany, researchers experimented with rotating cylinders to increase wing lift, though these experiments were fraught with technical difficulties and casualties. The author suggests that the 'flying discs' may be the result of this research, potentially having fallen into the hands of the Russians after the war. He concludes that the technology relies on gas-turbines and rotating parts, which provide superior performance and range compared to traditional gasoline engines. The report includes a handwritten annotation by an intelligence officer describing the report as 'Good' but the translation as 'lousy.'
