Very Heavy Bomber
The B-29 Superfortress revolutionized World War II-era bombers, enabling long-range missions over Japan. The "super bomber" could carry more payload and fly faster than the Army's B-17 or B-24 heavy bombers. The B-29 was also equipped with a pressurized interior, allowing crewmen to fly long distances in relative comfort. Two modified B-29s dropped atomic bombs on Hiroshima and Nagasaki, Japan, helping end the war in the Pacific. Another carried Chuck Yeager and the Bell X-1 rocket plane aloft for the first supersonic flight in 1947.
