Concorde

Concorde () is a retired Anglo-French supersonic airliner jointly developed and manufactured by Sud Aviation and the British Aircraft Corporation.

Studies started in 1954, and France and the United Kingdom signed a treaty establishing the development project on 29 November 1962, as the programme cost was estimated at £70 million.

Construction of the six prototypes began in February 1965, and the first flight took off from Toulouse on 2 March 1969.
