I agree about the nose loading part. Meanwhile, how does an engine with its nacelle compare to a marine container in terms of dimensions? Would it be easier or harder to load through the fuselage doors? I also assume that they will need a fixture or container for the engine if it was to be loaded into the cargo hold.
Engine is roughly 2.25m in diameter and 5.5m in length. So it would fit through the nose cone door, even with a modest fixture/container, with room to spare.
