Concorde Mach 1

In 1969, the French Concorde prototype 001 broke the sound barrier for its first time. The inaugural flight of the aircraft had taken place on 2 Mar 1969 in Toulouse, France. The first commercial passenger supersonic flights on 21 Jan 1976 of the British and French Concorde jets marked a brilliant technological achievement. The Concorde was the world's first airplane to be entirely controlled by computer. At first, environmental groups dennounced the Concorde's noise during takeoff and its fuel consumption. Its impact on international air travel was limited by the high costs of operating the aircraft. Only British Airways and Air France operated the aircraft. Their service ended with final passenger flights on 24 Oct 2003.
