Concorde

Concorde was a British-French supersonic passenger airliner that entered commercial service in 1976 and retired in 2003. Its delta wing and afterburning engines enabled sustained supersonic flight.

Delta wing: A triangular aircraft wing whose leading edges sweep back toward the fuselage. Concorde’s slender delta wing generated lift efficiently at supersonic speeds.
Sud Aviation Super-Caravelle: A proposed French supersonic transport developed by Sud Aviation in the late 1950s. It was the French design path that preceded the joint Concorde program.
British Airways: The United Kingdom’s flag-carrier airline, formed in 1974 from state-owned aviation companies. It operated Concorde on routes including London–New York.
Concorde effect: A proposed pattern in which buyers pay more for a product associated with national prestige or technological achievement. The term draws on Concorde as a conspicuous, costly symbol of technological ambition.
Turbojet: A jet engine that produces thrust mainly by accelerating a high-speed exhaust stream. Concorde’s propulsion system belonged to the turbojet family.
Bristol Type 223: A British supersonic airliner design developed by the Bristol Aeroplane Company. Its research and design work formed the British counterpart to Super-Caravelle.
Air France: The flag-carrier airline of France, founded in 1933. It was the other airline to operate Concorde commercially.
Concorde crash: The 25 July 2000 crash of Air France Flight 4590 near Paris, killing all 109 people aboard and four on the ground. The disaster ended Concorde’s previously fatality-free passenger service and accelerated its withdrawal.
Afterburner: A device that burns fuel in a jet engine’s exhaust to increase thrust. Concorde used afterburners during takeoff and to accelerate through transonic flight.
Anglo-French Concorde Agreement: A 1962 treaty committing Britain and France to jointly develop a supersonic airliner. It made Concorde a shared project and imposed major political and financial commitments.
