Some of the earliest stories about German flying saucers date back to an inventor named Victor Schauberger. Schauberger was born in Austria in 1885 and was considered by many to be a crackpot. Schauberger himself said, "They call me deranged. The hope is they are right..." Schauberger believed that machines could be designed better so that they would be "going with the flow of nature" rather than against it.
One of Schauberger's projects was to produce a flying machine, saucer shaped, that used a "liquid vortex propulsion" system. His theory was that "if water or air is rotated into a twisting form of oscillation, known as a 'colloidal,' a build-up of energy results, which, with immense power, can cause levitation."
According to stories Schauberger built several models (right), one of which was almost five feet in diameter and was powered by a 1/20 hp electric engine. Some reports indicated that one of the models actually flew. There are also reports that, according to letter Victor Schauberger wrote to a friend, a full-sized prototype of one of his designs was constructed using prison labor at the Mauhausen concentration camp. This craft flew on February 19th of 1945 near Prague and obtained an altitude of 45,000 feet in only 3 minutes. The letter goes on to say the prototype was destroyed by the Nazis before it could be captured by the Allies.
After the war Schauberger moved to the United States, where some contend he worked on secret projects for the U.S. government. He died in 1958, apparently claiming his ideas had been stolen.
Another German designer involved with the Nazi effort during the war was Rudolf Schriever. Schriever, along with some other engineers named Habermohl, Miethe and Bellanzo, apparently came up with several disc-shaped aircraft designs that used more conventional power sources than those Schauberger envisioned. One of Schriever's drawings shows an egg-shaped cockpit surrounded by a rotating fan-like disc that provided the lift. A Mieth drawing depicts a smooth flat saucer with an elongated hump on its back for the cockpit. Both would have been powered by jet engines.
As with Schauberger, there were reports that some of these designs were actually built. The Schriever machine was said to have been tested in 1945 and to have reached an altitude of 12 kilometers in a little over three minutes. It had a top speed of 2000 kilometers an hour.
There is no real, solid evidence, though, that a test flight ever took place and Schriever himself, who relocated to the United States after the war, indicated that any prototypes of the craft were destroyed, before flying as the Germans abandoned their facilities in the face of advancing Allied troops.
Stories also persist that the Germans's also had developed small automatized flying discs. One version was called the Feuerball. Another, capable of vertical takeoff, was referred to as the Kugelblitz. According to stories, these craft were only armed with devices designed to interfere with the electronics of nearby airplanes.
So were there really any German disc-shaped aircraft? It seems likely that there was certainly some experimentation with the concept within the Reich. Disc-shaped aircraft have several advantages, including low stall speed and low drag, even at high speeds. The rounded shape can also lower the craft's radar profile making it "stealthy." For these reasons German designers did consider using disc shaped aircraft, as did the U.S.
