Four hours on one engine.......jeezus, Cessnas can fly that long. What about the Pilatus?? I'm at the point, where I simply get tired of the one engine thing. So what?? One engine will get you where you are going, even on a twin, ETOPS wouldn't be in place if it didn't. Give me a twin over a 4 holer anyday, especially over the Pacific. That at least halves my chances that an uncontainted engine failure could destroy or severly damage the plane and force it down in the ocean.
Four hours on one engine is old hat.
