The Boeing 747: How a Bet on the Wrong Future Built the Right Airplane

When Boeing committed to the 747 in the mid-1960s, the conventional wisdom inside the industry was that the future of passenger travel belonged to supersonic transports. The Anglo-French Concorde was already in development, and Boeing itself was working on its own supersonic design. The prevailing assumption was that subsonic jumbo jets would have a short life carrying people before being relegated to cargo. That assumption shaped the airplane in a way its designers never fully anticipated. To make the 747 a good freighter for its expected second act, Boeing placed the cockpit on an upper deck so the entire nose could hinge upward and let cargo load straight into the main fuselage. That decision created the distinctive forward hump — and, almost incidentally, the iconic upper-deck lounge that became a symbol of jet-age glamour. The 747 entered service with Pan American in 1970. It roughly doubled the seating capacity of the 707 it followed, and by spreading the cost of a flight across far more passengers, it helped drive down the price of long-haul travel and opened international flying to the middle class. The supersonic future never arrived. Concorde flew, but high fuel burn, sonic-boom restrictions, and brutal economics confined it to a handful of routes. The "interim" widebody, meanwhile, anchored long-haul aviation for half a century across dozens of variants. Boeing built the 747 for a future that didn't happen — and in doing so built one of the most consequential airplanes that ever did.
