Spot on TC.
I saw what may have been the footage you refer to on BBC Alba's An Lá and I have just watched it again. It shows a heavily damaged lower cabin looking as though it were crushed by the momentum of the power train and top deck assemblies in the way that you describe.
This is consistent with the description given previously by a fire service officer who reported the work necessary to hold the aircraft together during retrieval.
