If you'd had your druthers for over water, transcontinental heavy passenger flights would you;

1) Add two additional powerplants or;

2) Stay the course with the current two powerplant aircraft.

Modern engines are far more reliable than those in service a few decades ago...even with only two you're still likely safer than with three or four old-school motors. How safe do you want to be, and what are you willing to pay for it?

Has their been an accident where having 4 engines vs 2, over the water, would have made the difference?

Does a 2 engine airplane have half the risk of engine failure when compared to a 4 engine airplane?

Also, does a 2 engine airplane have more excess thrust when compared to a 4 engine airplane?

Ask Sully.

Ask Sully.
Would the other one or two engines have also ingested geese?

I think the A380 may end up the last airplane with 4 engines for awhile.

With ETOPS time increasing, and efficiency of engines increasing, it makes more sense to have a larger fleet of slightly smaller twinjets than fleets of airplanes with 6-7-800 pax capacity.

It's also easier to fill planes, and supplement routes on the fly.

Ask Sully.
But if Sully was in a 4 engine plane, he wouldn't have taken off from LGA and instead, probably from JFK, where we all know, would have been void of the very birds that took his Airbus down.

Boom! Logic! Whooooo

It was a loss of all engines, not "two", so one would have to assume the exact scenario in a four engined airplane would still result in a loss of all engines.

At some TOGW, if a 747 suffered the loss of two engines, the outcome might still be in the river. A quad, just like a twin, only has to perform with OEI for take-off calculations.
