The document discusses the development and design of the supersonic Concorde aircraft. It describes how the British and French governments agreed in 1962 to jointly develop a supersonic transport. Two prototypes were built and the first flight occurred in 1969. Key design aspects included delta wings for stability at supersonic speeds, powerful jet engines, and a droopable nose for visibility during takeoff and landing. Concorde carried 100 passengers at twice the speed of sound but was retired in 2003 due to high costs and falling revenues.
