The US opposition to Concorde was, in the UK, perceived to be sour grapes if not self interested. There were of course, many detractors here who shouted white elephant etc . Dare I suggest ,that in some cases ,the same people who now knock the BBC . Concorde was very much a public sector encouraged project and that perception dealt it a blow in British opinion.
But all that apart it was a truly remarkable design and thing of beauty . It is said good design never dates and Concorde always looked as though it had just flown off the drawing board.
