Could somebody please confirm/clarify: was an engine(s) shutdown that was still producing significant thrust during this emergency?
Yes it was - according to the tapes the F/E shut down the engine with a fire warning before the Captain asked for the engine to be shutdown.
That engine was producing thrust.
Whether that early shutdown would have affected the final outcome I do not have enough information to make a qualified judgement - but certainly the F/E shut down an engine producing thrust before any command from the Captain.
That action by the F/E was not an action I would have expected from any F/E in another airline that operated the aircraft.
