The Aérospatiale/BAC Concorde () is a British–French turbojet-powered supersonic passenger airliner that was operated from 1976 until 2003. It had a maximum speed over twice the speed of sound, at Mach 2.04 ( at cruise altitude), with seating for 92 to 128 passengers. First flown in 1969, Concorde entered service in 1976 and operated for 27 years. It is one of only two supersonic transports to have been operated commercially; the other is the Soviet-built Tupolev Tu-144, which operated in the late 1970s.
