Concorde was jointly developed and manufactured by Sud Aviation (later Aérospatiale) and the British Aircraft Corporation (BAC) under an Anglo-French treaty.
Twenty aircraft were built, including six prototypes and development aircraft. Air France (AF) and British Airways (BA) were the only airlines to purchase and fly Concorde. The aircraft was primarily used by wealthy passengers who could afford to pay a high price in exchange for Concorde's speed and luxury service.
Among other destinations, Concorde flew regular transatlantic flights from London's Heathrow Airport and Paris's Charles de Gaulle Airport to John F. Kennedy International Airport in New York, Washington Dulles International Airport and Grantley Adams International Airport in Barbados; it flew these routes in less than half the time of other airliners.
