Pilots' mess

The closest of UFO , it was this singular plane. In June 1939, German Air Minister, Ernst Udet, attended a demonstration flight of the AS-1, a circular plane with wings and was so impressed that encourage the designer Arthur Sack to continue with the investigations. 
Sack built four prototypes later, reaching the final model AS-6, which was built in Mitteldeutsche Motorwerke and completed in the laboratory Flugplatz-Werkstatt Luftwaffe base in Brandis, in early 1944. 

Her seat and landing gear of a Messerschmitt 109B, and the propeller of a Messerschmitt 108. After having an accident on his first flight, and suffer many problems of stability in the six subsequent flights were introduced 70 kilos of ballast in the tail, improving considerably. 
But an Allied bombing on the base during the winter of 1944, destroyed all the prototypes, and here I project. Later, when American troops entered Brandis, found no trace of the project.
