pontiflex,
I think that your suggestion of what may have happened is totally unfounded and equally unacceptable. Trying to allocate blame with absolutely NO proof is ridiculous.
From my experience, people who are relatively inexperienced but who have been briefed properly, will do exactly as told. If EJECT, EJECT, EJECT is commanded I would not expect the seat to still be there by the 3rd EJECT.
Equally, I would not expect an inexperienced person to recognise when a dangerous situation, as in this accident, was developing. I would not necessarily expect an inexperienced person to initiate ejection with no command from the pilot.
I totally agree with BV that ditching would be out of the question when in a bang seat. SAFE HEIGHT, SAFE SPEED, WINGS LEVEL - EJECT
