I think there is a crossed purpose amongst some posters here. What we are talking about is getting a concorde back into the skies as a tribute to those that designed and built her, and to celebrate the finest engineers of their generation who overcame all the "cannot be done" obstacles to actually get it done. A display of true grit and determination if you like, and that isn't forgetting that the French did have more than a passing interest in the design & build as well. But to look at the British angle it was a one off, and something that the British nation should be proud of! Like him or loath him, Jeremy Clarkson has it right when he says that something that well engineered has a soul of it own!
But let's forget about the sentimentality of getting her in the air again, we are not talking about putting paying passengers on board, and re-starting BA001/002 every day. We are talking about an aircraft flown to please the crowds at airshows. No-one suggest that we return the spitfire to front line service, but we are happy to see them flying at displays all around the country in the summer, in that we as a nation can pay tribute to a machine that we in fact owe a great deal to, and the same rule of thumb applies, and that being the case, then surely Concorde can return to flight on a "permit". If this is possible, then why not. Let us not forget that according to a recent thread on the site that the French are continually ensuring that one is available should the need arise. Perhaps the time to start doing that is now. I understand that all the machines are without the engines and certain other parts, apart from AC at Manchester that by all accounts is still fully equipped. So why not?
