Good answer David C., and in most respects I agree, with one small difference.
I was very aware of the development of Concord from the very beginning, and was the proud recipient of a great deal of data on the soon-to-be test flown pre-production prototype.
I was also aware that, at that time in the early 60's, Boeing was heavily into it's version which was code-named the SST ( cunning that - Super Sonic Transport ). The board of Boeing was in some disarray over some awesome cost over-runs, but all the while kept in check by the belief that they would first into the market. Also their 'bird' was quite a lot bigger, and thus commercially more viable.
Well, we all know what happened, the Anglo-French consortium started test flights at Fairford while Boeing was still on the drawing board, and not making much headway. The project was scrapped and large amount of hubrus and downright sour grapes poured forth from the Septic side of the pond.
The campaign kicked off in New York, with Kennedy ( the former Idlewild ) banning Concorde flights, due to noise. There is no question that she does make a hell of a racket , particularly on take off, but she is still the most beautiful and inspiring commercial passenger transport ever built.
And.............just to the entire waffle of my chest......I have often wondered what the real effect of Marcel Dassault's major share-holding in Boeing might have had to do with the whole yarn ???
The final word on supersonic passenger flights ? Maybe it will be a HOTOL or similar that will eventually provide a realistic way to pop us from London to Sydney in a couple of hours or so. If they can de-bug plasma drive, or come up with some other non-dinosaur burning propulsion system that is environmentally sane, then it could be on the cards.
It should also be remembered that the technology that brought us Concorde also, like the NASA space program, brought an extraordinary array of advances in many other fields.
