The B-29 was one of the largest aircraft to see service during World War II. It was
one of the most advanced bombers of its time, featuring innovations such as a pressurized cabin, a central fire-control
system, and remote-controlled machine gun turrets. Though it was designed as a
high-altitude daytime bomber, in practice it actually flew more low-altitude
night time incendiary missions.
