Carnage are you talking about the enormous sum of £1 that BA paid for Concorde?
You actually take notice of what Richard Branson says?
As far as i'm aware BA paid for Concorde in full. They also put millions of pounds in maintaining and flying her, not forgetting the cabin and airframe upgrades that she recieved in 2001 to make her flyable once again.
She is BA's property, live with it.
