While CG shift was a factor in that accident
the direct cause was the military vehicle breaking loose from its restraints then penetrating the rear pressure bulkhead and
striking the stab trim jackscrew with enough force to disable it and the elevators
The crew had no means of controlling pitch through the primary flight controls
