Concorde was a famous passenger plane that flew at about twice the speed of sound — faster than any other airliner the public could board. It looked unlike ordinary jets: long and very thin, with a sharp pointed nose that could tilt down so the pilots could see the runway. Britain and France designed and built it together, and that shared work is why it has this name: French concorde means agreement, working as one. British Airways and Air France flew it. Tickets cost a great deal, and for years a Concorde flight was fashionable as well as fast: London to New York in about three and a half hours instead of seven or eight. Because you outran the clock heading west, you could land with the local time still earlier than when you left, which felt almost like a trick. Though actually, it was never a plane for ordinary holiday crowds. It was noisy on take-off, hungry for fuel, and extremely expensive to run. After a crash in 2000 and rising costs, both airlines stopped Concorde flights in 2003. The aircraft now sit in museums. Write it with a capital C: it is a name for that one type of plane, not a common word for any fast jet.
