All the Frech Concordes have had similar fates to those prescribed for BAs. One went to Airbus France, another across the pond, one to a German Museum, one at Le Bourget, the other at Charles de Gaulle. I'm not sure where the others went, but none have flown since their final positioning flights.

The BBC indicated that this afternoon, engineers on the BA conc at Manchester would begin to dismantle her engines, and she would no longer be airworthy by the end of today.
I presume BA will keep all the engines just to make sure no-one else could get their hands on them.
