Though of course there should really be zero chance of that happening either:
Interestingly, the Max 9 sticks out even farther behind the MLG than the -900 does, though I've never seen a photo of one of those with a tail steady. Presumably the heavier and slightly farther forward engines reduce the risk?
It's more to do with the length. Engines generally very close to the CoG/M. In simple terms 10T of mass 1M away is the same as 1T 10M away. It's a little more complicated than that though, and that is just in a static state.
