Rainboe:
For a trijet to cross anywhere with 3 engines running is, normal..that's why it's called a 'TRIJET'!!
To continue on two engines for 10 hours is, not really contemplated. You would probably and certainly be looking for a 'suitable' airport.
Now, to consider that a B744 is equal to a trijet, just because it lost 1 eng is not very realistic...me thinks? (systems,fuel consumption, etc).
If a 'trijet' lose a second engine, it becomes an emergency situation as, is in the case of the B744 on two engines.
As I said before, this crew made the decision to continue, and that was their prerogative. The opinions, although varied and controversial for some of you on this forum, have validity and are not without consideration.
I think it's time to wait for the final outcome of this investigation on this 'incident'. Over and out!!!
