You can't hang onto the good times. Enjoy them, savour them, then let them go gracefully. If it hadn't stopped now, it would have stopped in a few years. It was never going to be around forever and it's had a good innings, so what's the difference?
I'm sure they wept the same kind of tears about the Zeppelins, but the reality is that even before the Lakenhurst disaster the cost of a passenger seat mile meant their days were severely numbered and if Concorde didn't suffer from the same sort of problem we wouldn't be having this discussion now. Blame whoever you like -- the French, the Americans -- but it's a hard capitalist world out there and Concorde doesn't cut it.
Sad, but self-evident.
