Tupolev ANT-20
The Tupolev ANT-20 Maxim Gorky (Russian: Туполев АНТ-20 "Максим Горький", sometimes romanized as Maksim Gorki) was a Soviet eight-engine aircraft, the largest in the world during the 1930s. Its wingspan was similar to that of a modern Boeing 747, and was not exceeded until the 64.6-metre (212 ft) wingspan Douglas XB-19 heavy bomber prototype first flew in 1941.
