Thanks for the CV, Jacko, but I am NOT an expert on Concorde. I really hope that someone will prove that I'm talking bollocks and that the crew neither took off above max certificated take-off weight, nor handled the emergency in anything other than an exemplary manner in an impossible situation.
Sadly, and much as it pains me to say so, I cannot yet reach that conclusion.
RIP F-BTSC and all who flew in her, but the important thing - the really important thing - is that the lessons learnt will mean that such an accident can never be repeated.
