Good memories: thank you, sir.
Airclues: again, thanks for the insights.
RG: If I understand your question correctly, your question regards the possibility of things moving on the inside of the hull that might cause damage to control linkage or to various electro/hydro/mechanical connections to the flight control system that controls the horizontal stab and /or elevators?
I think that someone addressed that a few pages back, let me check for a link.
EDIT:
Here were some points on what happens when the load shifts, with the last one asserting damage to a particular sub assembly.

Not sure if that has been answered, but someone else does seem to think that the possibility is there. I don't know the physical layout of the tail sub systems and linkages, so I can't comment.
