Just for Branson and others benefit, Concorde is an Anglo-French concern ( Concord - literal dictionary definition is ' of one heart' ). If his lordship would like to see Concorde continue to fly why doesn't he go and badger Air France for some of theirs, their retiring at the end of this month I think. Concorde is about the aircraft not about the company.
Personally I agree with a few of the posts above. He's a publicity seeking ****.
If this wasn't more about giving BA a bloody nose rather than keeping Concorde flying he'd be spending some time down in France talking to AF I would think that they are just as passionate about the aircraft as the British are.
