The 'Schriever-Habermohl' flying disc developed between 1943 and 1945 consisted of a stable dome-shaped cabin surrounded by a flat, rotating rim. Toward the end of the war, all the models and prototypes were reported destroyed before they could be found by the Soviets. According to postwar U.S. intelligence reports, however, the Russian army succeeded in capturing one prototype. After the war, both Schriever and Miethe, another German scientist involved in the design of flying disks, came to work for the US under ‘Operation Paperclip’. Habermohl was reported, by U.S. Army Military Intelligence, as having been taken to the Soviet Union.
