I'm thinking in terms of a sudden violent event - such that the inertia to be overcome in pitching the nose up would create enormous tension at the top of the cabin.
In terms of the flight recorders, I may be pushing the plausibility envelope, but I see some possibility that their connections were destroyed by the sudden movement of the HS internal structure beyond its normal operating limit.
