It is reported that many passengers were found in their seats which had detached from the mountings. The seats attachments are stressed to a little beyond the crash G tolerance of the human body. Whilst portions of the fuselage appear intact the fractured seats bear witness to the forces involved. The crash was patently not survivable.
I am however intrigued by the resting place of the tail section. Harsh pilot handling has contributed to separation of the empennage in the past... perhaps here also ?
