Why didn’t it succeed?
Concorde flights came to a screeching halt after only 27 years of operation on October 24, 2003. The reason? Excessive cost, high fares, and loud noise. On a regular flight, Concordes consumed 6,771 gallons of fuel, which quickly exceeded the profit made from the flight. In addition to that, only a total of 20 Concordes were built and no airline ordered them except for Air France and British Airways, who had to as they were state-run airlines at the time.
Oh, and a 2000 crash that killed everyone on board (109 people) and four people on the ground.
True. And the fact that because of sonic boom it was not allowed to fly supersonic above land. Only when it reached the atlantic supersonic was allowed. So it’s practical use was quite limited.
Boom is working on a ‘successor’ to the Concorde without the loud boom when going above speed of sound.
That’s specifically a US regulation, but costly as coast to coast across the US would be the only other viable route.
Possibly only existing as a reg because it wasn’t an American plane…
