Has anyone ever thought of a non-flyable Junker JU 290?
From the wiki:
"The A-3 version followed shortly after with added navigational equipment and probably the heaviest defensive armament of any World War II aircraft; it was fitted with two hydraulically-powered HDL 151 dorsal turrets armed with 20 mm MG 151/20 cannons, with a further 20 mm MG 151/20 and a 13 mm (.51 in) MG 131 machine gun fitted in a gondola beneath the nose, and a 20 mm MG 151/20 fitted in the tail operated by a gunner in a prone position. Two 13 mm (.51 in) MG 131s were also fitted in waist positions (Fensterlafetten). The A-3, along with the A-2, also featured large auxiliary fuel tanks in the fuselage. Both types retained the rear loading ramp so that they could be used as transports if need be."
Would be nice to battle a formation of them.
