I wonder if it's a coincidence that the Mughal invasion in the early 16c happened after the Indian population halved over the preceding two centuries. Perhaps the reduced population made India an easier target for their expansion.

I suspect it's because they are inside the aircraft so have several layers of crumple zone around them. It is not, generally anyway, just the exposed box hitting an immovable object.
