I believe AA was taken out of service after its last flight on August 12th 2000 and had been languishing as a hangar queen at LHR since then.So it was not likely to be in a fit condition even for a ferry flight.Happy memories of that airframe my only ever passenger Concorde flight JFK-LHR many year ago a truly fantastic passenger experience much akin to flying in a noisy Bac111.Take off struck me as a very agricutural experiece I,ll never forget it.Glad I did it seemed an extravagence at the time and that was a staff deal.
