And now you're being silly. It doesn't matter a damn whether it's piston or jet or turboprop or elastic band.
There are all sorts of possibilities for double engine failure that are no fault of the pilot.
What's more, I have limited faith in most MEP's ability (and in the case of some MEP's no faith at all) to remain aloft even with a single failure. Does anyone here know the single-engine stabilising altitude for a Twincom? I don't, but I know that in a BN2 it's sea level.
I also have no faith whatsoever in the abilities of the press to get the details right. To 99.9% of journos, a multi-engine aircraft going down after engine failure HAS to be all engines failing.
My point is that there is no evidence whatsoever (yet?) of pilot error in this case, that there are several possibilities that would have this result without any pilot error at all, and that for someone here TWICE to accuse the pilot in this case is uncalled for as well as being a possible libel.
