Indeed, the very best of luck to BA and their continued operation of the magnificent Concorde.
Specualtion regarding the ATOW, RTOW and whether the AF accident aircraft was over both MTOW and RTOW has not been to suggest that this was a primary cause of the accident - although the effect on tyre safety margins of operating above MTOW might be of note. However, if by virtue of the aeroplane being on the ground and hitting the FOD beyond the point at which it would have become airborne had it not, as has been suggested, been grossly over RTOW then the MTOW/RTOW/ATOW debate would be significant.
What is of great concern to many is the 'culture' which may exist in a company whose aircrew either failed to check the effect on their aircraft performance resulting from a significant wind velocity change, or who failed to act correctly when they did know that they were both over MTOW and certainly RTOW. As is a culture which apparently accepts uncommanded engine shut downs.
