>It was an old plane. It was marginal economically. It had a fatal accident. And then, just as it was returning to service, the travel slump after 9/11 happened. I agree that all those are the primary retirement factors but I did not want to bring them up as they where being discussed elsewhere in the comments. I'm interested to see that people where complaining about the potential of Concorde stratospheric pollution all the way back in 1972[1]. Maybe it was not so much a reason for retirement but one of the many reasons the concorde received such a poor public reception in the 70s. I think Boom has some serious hurdles ahead of them in this regard. Environmental regulations have done nothing but grow since the 1970s and many countries where outright banning the concorde from their airspace then.
