All interesting stuff and of course a tragic accident , but such an iconic aircraft will always attract such ongoing debate.
One thing I may have been interested in if I was a CO lawyer, would be something I read in another Concorde thread on this site, and I have no reason to doubt the validity of the claim, as the person who placed the information seems to know his onions on the operation of Concorde's engines.
IIRC he mentioned that Olympus engine 4 was kept well below max thrust until 80kt was reached, meaning the PF would have to adjust for the inclination of the greater thrust on the left hand side of the aircraft steering the nose towards the right.
It seems a little strange that the aircraft seems to have actually headed to the left of the runway very early according to some reports....
Just a thought from a humble SLF
