Tupolev Tu-70

The Tupolev Tu-70, NATO reporting name Cart, was a Soviet four-engined passenger airliner derived from the Tu-4 bomber, itself an unlicensed reverse-engineered copy of the Boeing B-29 Superfortress. Designed just after the Second World War, it reused outer wings, engine cowlings, flaps, undercarriage and tail from two B-29s that had landed in the Soviet Union, but had an entirely new fuselage, the first pressurized fuselage in the country, and a low-wing layout. Cabin plans ranged from a government VIP version to a 72-seat airliner. It first flew on 27 November 1946 and passed state trials in December 1947, but was never produced because factories were committed to higher priority types and Aeroflot was content with the Ilyushin Il-12. It was scrapped in 1954.
