William Boeing started his airplane-making business in Seattle on July 15, 1916. Boeing supplied the two iconic Allied bombers of World War II – the B-17 Flying Fortress and B-29 Superfortress.

After the war, Boeing launched the jetliner age with the 707 and jumbo jets with the 747. The company also remained a major defense contractor, merged with such previous competitors as North American Aviation, Rockwell and McDonnell Douglas, and moved its corporate headquarters to Chicago.

Europe's Airbus eventually emerged as Boeing's only competitor for large commercial aircraft. Today, the Boeing 737 competes against the Airbus A320; the 767, 777 and 787 Dreamliner against the A330 and A350 XWB; and the 747-8 against the larger A380.
