The Concorde was the fastest commercial passenger aircraft in history, typically completing the London-to-New-York route in under 3.5 hours. To put this in perspective, a standard subsonic flight today takes roughly 7 to 8 hours. The Concorde cruised at a staggering speed of Mach 2.04 (about 1,350 mph or 2,180 km/h) at an altitude of 60,000 feet. The all-time record for the fastest transatlantic crossing by a passenger jet was set by a British Airways Concorde on February 7, 1996, flying from New York (JFK) to London (LHR) in just 2 hours, 52 minutes, and 59 seconds, aided by a strong tailwind. While the Concorde was retired in 2003, its legacy as a supersonic marvel remains unmatched in 2026. Passengers on these flights could actually see the curvature of the Earth from their windows while flying twice the speed of sound, arriving in New York "before" they left London due to the five-hour time difference and the aircraft's incredible velocity.
