Yes, I had seen the video, but although he states things with apparent confidence his view is not supported by the formal report.
Consider the final report wording quoted in my post 2025:
Before line-up, the crew carried out fuel transfer so as to bring the CG to 54% for takeoff. During this operation, the fuel burnt from the feeders during taxiing was replaced by the fuel contained in tank 11.
The French (definitive) version uses "a effectué" rather than "carried out" which suggests they completed that task. If so, why abandon the standard Concorde procedure?
The BEA went to some trouble to establish the amount of fuel in tank 5 at the time of rupture. The process they describe makes no mention of any transfer from tank 11 into tank 5, or indeed any transfer of fuel into that tank during the take off run. In fact they concluded that there was a reduction of 21 kg as a result of normal transfer from tank 5 to tank 1 when that tank became depleted.
