This mighty company evolved from the humble Pacific Aero Products Company, incorporated in Seattle in July 1916 and renamed Boeing Airplane Company in 1917. Boeing's 100-year history spans decades of rich achievement and technological development, first with the manufacture of sea-planes, then fighters and, from the 1930s onwards, huge bombers, innovative transports and finally, gigantic airliners, missiles, rockets and vehicles for moon exploration. Boeing constantly evolved, setting out to develop an entirely new jet transport, and in 1954 the innovative 707 appeared. The 727 and 737 airliners quickly followed and in 1969 the revolutionary 747. By 1975 the "Jumbo Jet" was being produced in seven different models and new versions continue to be developed to this day.
