Tough landing when you know you can't really use the one engine you have left to provide much............if any reverse thrust.
Airliners use much less runway then people think to land, especially at sea level. At 8,600' thats plenty of runway thus the certification of ETOPs Diversion for the 777. Even a 747 fully loaded only needs about 5,000'. When your flying they hit the brake and reverse thrust more to make a particular taxi way and get to the gate then they do to stop the plane safely.
That single engine on the 777 is the most powerful engine ever put on an airliner. I'd be far more worried about weather then a single 777 engines being able to stop in 8,600'. I finished my career at an airport. Its actually very unusual for an airliner to lose an engine and I never remember a 777 doing so. Normally its a hydraulics problem, occasionally flaps, once we had a Embraer have to slide land on its front two wheels cause the rear one wouldnt go down. The Pilot split the yellow lines and stayed there, a beautiful job.
For some reason its unusual to have a mechanical on a larger airplane. Those 70 to 190 seat CJs, EJs, MDs, 320's, 737's, they keep them flying and making money all day long. They stop, unload, load back up, and are off again all day long. Those routes are where the real moneys made and they squeeze every cent they can out of those airplanes which is why they are the ones with mechanicals most of the time. Probably.
