Dr Alexander Lippish holding its greatest (maybe) contribution to flight, the Delta wing. The DM.1 was a proof-of-concept glider intended to test the soundness of a posible delta winged interceptors, specially Lippish’s powdered coal fueled (!!) ramjet-engined P.13a. At the end of the war the almost completed prototype was captured by the Americans. “Flight” tested in the NACA full-sise wing tunnel it proved to be everything Lippish had claimed…..after a lot of modifications. Lippish also came to the US and with his help a whole family of Deltas soon appeared at the Convair company’s stables.
Herr Doktor looks just dandy in this postwar pic.
