Two points which may calm down these wild directions the thread is tramping:
1) It is to be hoped that heading v time will be recoverable from the FDR, and then all will be revealed
2) Without wishing to cause extra distress to the bereaved, the main value to the enquiry of body recovery from the sea bed will lie in examining the damage to the skeleton to try and ascertain the nature of the impact with the sea (and seating state) if that cannot be determined from the FDR. Thus the 'condition' is secondary, and I would hope that after a sufficient 'sample' has been recovered the wishes of some of the bereaved can be observed.
