Evolution of the 747

The U.S. Air Force's request for a larger cargo jet led to the development of the C-5 Galaxy, but Boeing pivoted to create the iconic 747 passenger aircraft. Initially envisioned as a double-decker, safety regulations and cargo capabilities shaped its final design, resulting in the distinctive hump that characterizes the 747 today. Despite doubts about its longevity in passenger service, Boeing prepared for a future where the aircraft could easily transition to cargo use.
