ETOPS has absolutely nothing to do with this. 4 eng jets are not bound by etops, but i can bloody well guarantee that if I was flying a 380 that had an engine failure and was shaking the jet as badly as was happening on the 330, I would have landed at the nearest suitable - ie Learmonth.
Besides, doesn't the manufacturer have capital letter LAND ANSA in amber on the ECAM for the 330? (It did when I used to fly em). Looks like a lot of commentators have forgotten about that thing called airmanship, and CDF.
As for the "saying a prayer" bit - well if that isn't the most terrible display of command leadership, and that that is endorsed by any actual captains here, then I weep for the future of aviation.
