1969 1st Flight of Concorde

The Concorde was a supersonic passenger airliner jointly developed by Britain and France, symbolizing close Anglo-French tech­no­logical cooperation. Designed to fly faster than the speed of sound, it could cross the Atlantic in about three and a half hours. Concorde made its first flight on 2 March 1969 from Toulouse, France, followed by the British prototype from Bristol on 9 April 1969. Entering commercial service in 1976, it was operated primarily by British Airways and Air France until its retirement in 2003, re­nowned for speed, elegance, and innovation.
