This WW2 German flying nightmare was a low speed test rig for a 20 degree forward swept wing design. Designed in 1943, the prototype was lashed together from a wide variety of parts. The new wing was mated to the fuselage from a Heinekel He-177, the tail of a Junkers Ju 388K, and two nose wheels from a shot down American B-24 Liberator. The landing gear was fixed and spatted, four Junkers Jumo 004's were mounted as engines. The top photo was taken by an Allied pilot.
