Bachem Ba 349 Natter (colubrid) was a World War II era German experimental point-defense rocket-powered interceptor aircraft which was to be used in a very similar way as unmanned surface-to-air missiles. After vertical takeoff which eliminated the need for airfields, the majority of the flight to the bombers was radio controlled from the ground. The primary mission of the (inexperienced) pilot was to aim the aircraft at its target bomber and fire its armament of rockets. The pilot and the main rocket engine should then land under separate parachutes, while the wooden fuselage was disposable. The only manned test flight, on 1 March 1945, ended with test-pilot Lothar Sieber being killed.
