11/30/2009. Remarks by Johan Visschedijk: "Even this ultimate extrapolation of the Boeing B-29 was abandoned despite its excellence, because of the dramatic potential of the gas-turbine powered Tupolev Tu-95. Powered by four 4,300 hp VD-4K 24-cylinder supercharged engines the sole Tu-85 bomber aircraft first flew on January 9, 1951."
