Yeah, the music was good at parts but then it seemed like a CD was skipping? Anyway, this video made me wonder, how low to the ground are the inner engines (2 and 3) of A346. They seemed unusually low at the end when they took it out of the hangar painted and everything? How low are the 777 engines. I pressume somewhere in the 5 to 10 foot range right? Also, if they are that low, isn't it possible sometimes on a rough landing the wing and engines might shake a lot and cause the engine to hit the ground? Also maybe from excessive winds during touch down? Any answeres would be greately appreciated.

I don't know about the A-340-600 inboard engines, but the B-777 engines are only about 18" off the ground, at max gross ramp weight. My guess is the A-340-600's inboards are in this same 18"-24" range from the ground. This is most likely the same for the A-340-500.

When I was flying the KC-135A, the inboard engines were 20" from the ground (at MGW). But it was the outboard engines that were the limiting bank angle factor, even though they were 54" [4.5'] off the ground. In a cross wind landing, where you keep a wing low into the landing flair, the maximum bank angle you could have was 6 degrees. Anything more than that and you would drag an outboard engine on the runway, not good for a long flying career in the USAF. In the KC-135R, I believe this bank angle is reduced to just 4 degrees befor dragging an engine. But, in the KC-135R, the limiting factor is the inboard engines as they are only 12" above the ground.

The B-747 is a little more forgiving as their inboard engines are 20"-24" above the ground, about the same as the A-340-500/600.
