Why are some people still going on about fuel icing, contamination etc etc.
It is clear from the report that the engines did NOT fail - they just did not respond to autothrottle / thrust lever commands when the thrust was supposed to come up at 600ft.
I for one will wait for the official report and see what BA tells us in the meantime. I agree that this will probably turn out to be a one-off event - the 777 is a well engineered and very well thought out aeroplane.
