B-29 Superfortress' served as long-range, propeller-driven heavy bombers that carried crews of 10-14 and were flown toward the end of World War II and during the Korean War. Built by Boeing, it was one of the largest aircraft to have seen service during WWII. At 70,000 pounds, and 135,000 pounds fully loaded, it was the heaviest production bomber built. It could cruise above 30,000 feet at 220mph, out of range of flak and most enemy fighters. The B-29 had many innovations. It was the first production aircraft to have fully pressurized crew compartments. It also had a central fire-control system controlling remote-controlled machine gun turrets.
