The development of the jet engine represented a quantum leap in aviation, and revolutionised commercial aviation. Although first developed for fighter aircraft, this engineering triumph changed the world and led to the development of the jet airliner - especially the one which would set the pace for long distance air travel for the next decade - the Boeing 707. Thereafter America supplied the world with jet transports, creating the international network of air routes upon which the whole world has come to depend. Then Europe responded with the Concorde.
