Bachem Ba 349 Natter

The Bachem Ba 349 Natter (Viper), a semi-expendable, vertically-launched, piloted missile, was one of the several desperate yet ingenious measures improvised to defend the German skies. The small interceptor was designed by a team headed by Erich Bachem. The Ba 349 was built using bonded and screwed wooden parts, a simple metal structure and armored cockpit. The heart and soul of the aircraft was of course the internal Walter 109-509A-2 liquid fuel rocket (the same as that of the Messerschmitt Me 163. Four external Schmidding rockets were used for launching boost, providing a combined thrust of 4,800kg for 10 seconds before they were jettisoned. Bachem proposed that, as American bombers approached their target, the Ba 349 would be sent soaring vertically through the formation. The pilot would pick one bomber, fire his whole batch of twenty-four 73mm Hs 217 Föhn (Storm) unguided rockets, use the remaining thrust to climb higher past the bombers and turn back for a ramming attack. Supposedly the pilot could trigger a mechanism to release his seat from the fuselage with the rocket motor right before impact.
The "simple" ejection system, however, did not work and the impractical ramming proposal was dropped. The only parts that were saved were the pilot and the rocket motor for re-use. In October 1944 pilotless tests from near-vertical ramp and piloted gliding flights were started. On 28 February 1945 the first manned flight was attempted, resulting in the death of test pilot Oberleutnant Lothar Siebert when the cockpit canopy flew off, and the Ba 349 crashed. Ten Ba 349s were stationed at Kirchheim, but the advancing American forces overran the launch sites before any bombers could be intercepted.
