True That The Boeing 747's Iconic Hump Came To Exist By Accident?

The long-running belief that the Boeing 747’s distinctive “hump” appeared by accident doesn’t hold up, according to the design logic outlined here. In the mid-1960s, as airlines bet on a future of supersonic intercontinental travel, Boeing chief engineer Joe Sutter and his team shaped the 747 to protect the investment needed for a widebody aircraft. Rather than a styling afterthought, the raised upper deck was engineered to enable straight-in cargo loading of standardized intermodal containers—supporting a continuous tunnel-like cargo bay from the nose to the aft pressure bulkhead. The approach also reduced the need to disconnect flight systems during nose-door operations.
