To be perfectly honest if it were ever to fly again I wouldn't want it flying over my house!
But correct me if I'm wrong don't all the BA Concorde's remain owned by BA? ... They weren't willing to sell them in 2003 and I doubt that anything has changed their minds.
As for the AF Concordes, well Le Bourget are unwilling to sell, one is in a field near ORY, one is on stilts at CDG, one is on a rooftop in Germany, a couple in TLS, have I missed any?
