2 March 1969
On this day in 1969 the world’s first supersonic passenger aircraft, Concorde, had its first test flight.
Concorde was a joint initiative of Aérospatiale and the British Aircraft Corporation as a product of an Anglo-French government treaty. Concorde entered service in 1976 and continued commercial flights for 27 years.
Concorde had a cruising speed above Mach 2 and made the London to New York trip in under 5 hours which, allowing for time zones and the direction of travel, meant that you arrived at your destination before you left according to local time.
Concorde was finally retired in 2003 after its only crash, an Air France Concorde which exploded on takeoff in 2000.
