exvicar, I'd rather be on an ETOPs aircraft most of the time, its certified to higher standards, the engines have to have higher reliability, and other than the engines, it has to have better fire supression ability, in addition to numerous other additional standards. My understanding is that these redundancies are going to be applied to 4 and 3 holers.
why on earth you would continue with an engine failed for unknown reasons, when you have several perfectly useable, main airports nearby is beyond me. Yes it can fly on 3 engines ok, and yes it can struggle on 2, the fact is you have had some pretty significant malfunction/abnormal indication...and you cant really be certain as to what caused it.
why risk it, for saving some $$$.
