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.
I also think it’s the younger folks who may not know what older folks already knew. OP was maybe too young to remember about Concorde.
Im nearing 40 and never knew about it because:
Probably, I still remember my physics teacher using the Concorde as part of a quiz.
