The Concorde was world’s first supersonic passenger jet and was first flown in 1976 and retired in 2003. It was capable of Mach 2.04 (~2,179 km/h or 1,354 mph). A normal subsonic service took around 7-8 hours to fly from London to New York, but Concorde’s average flight time is around 3 hours 30 minutes, but can be slightly longer if the aircraft needs to hold before landing at the local airports. The fastest ever time for the crossing, the fastest ever set by a passenger aircraft, was 2 hours 52 minutes and 59 seconds. Let’s hope that super jets such as the Spike will revive the supersonic passenger flights.
