"I thought the rumour was that AG would be the one to be kept flying, instead of it being left in Barbados?"
That was the rumour in the local news media here last week.
Some of that media has now changed its mind and plumped for AF, presumably on the basis that AG might have gone to Barbados before any final decision is made about flying displays and the like.
I don't know which, if either, of these two would be the a/c that would be kept operational in the event of such a joyous happening.
I suppose it might be the local press just trying to look for a new angle that is not really there.
Visual,
AF was one of the three Concordes that did the final arrival at LHR on Friday (the Biscay flight I think).
