I'm going to ask/explain this as best I can; I'm sure I have some fundamentals wrong here.

Spaghettification is a phenomenon which occurs only in stellar-mass black holes owing to the immense gravity gradients experienced when approaching the event horizon. I have read elsewhere that in the case of supermassive blackholes, one could cross the event horizon and travel a measurable amount of distance toward the singularity without knowing until it is too late, whilst remaining in one piece.

This previously asked question sprung to mind - Fighting a black hole: Could a strong spherical shell inside an event horizon resist falling in to the singularity?Fighting a black hole: Could a strong spherical shell inside an event horizon resist falling in to the singularity?

I understand clearly, from the answers to that question, that forces holding matter together cannot propagate faster than light, so, my question is:-

How can someone/thing travel past and beyond the event horizon of a supermassive blackhole and travel an arbitrary distance when, in my understanding, they should effectively vapourise once the event horizon has been crossed?
