Lager Heuberg military training area near Stetten am kalten Markt, of Bachem Ba 349 Natter M23 (a vertically-launched bomber interceptor) failed when Oberleutnant Lothar Sieber, 22 (a volunteer), was killed as rocket-powered aircraft reached about . The cockpit canopy detached; the Ba 349 nosed over onto its back and fell about , killing the pilot. No cause for crash was determined, but it was thought that the improperly-latched canopy might have knocked Siebert unconscious. Three successful manned flights subsequently took place and a group of the fighters were readied for intercept missions, but advancing U.S. 8th Army armoured units overran the launch site before the Natters could be used. Two Bell P-59A-1-BE Airacomets of the 29th Fighter Squadron, 412th Fighter Group at Muroc Army Air Field, California, collided in mid-air over the Mojave Desert near Grey Butte Army Airfield during an anti-aircraft tracking exercise. 2nd Lt.

Dreher with a crew of three from night fighter unit 13./Nachtjagdgeschwader 3, was the last Axis aircraft to crash on British soil during World War II. Confused by auto headlights, the fighter hit a tree while attacking the airfield at RAF Elvington and crashed at Sutton upon Derwent, Yorkshire; all four crew members were killed.
