I have been studying the photos of the stuff hanging out damaged area and I am curious to all the references to baggage. I can't see any presence of a container - surely some of it would be visible? This leads me to think it is freight on a pallet and the stuff that looks like wiring is actually the parts of cargo netting. You can see what is maybe netting around the "packages".
Probably irrelevant I know but it did cross my mind that this incident may be DGR related. Unlikely that a pallet would shift anyway let alone in a lateral direction, and if it is skin failure due to corrosion (which I have read the posts about - very informative) would the vacuum from the decomp be strong enough to pull netted down cargo off a pallet towards the hole?
Just my thoughts and obviously speculation.
