Flying High

The B-29 Superfortress was one of the most technically advanced American planes used in WWII. The aircraft was the first to be constructed of a new aluminium alloy that added zinc, to prevent cracking, to the usual lightweight alloy of aluminium and copper. The heavily armed, long-range plane could fly much higher than most aircraft of the time, at up to 33,600 ft. It was B-29s that made the famous supply runs over the Himalayas to China during WWII.
