Regarding lack of occupant preparation...
mm43...
There are some indicators that will help, e.g.
- Those bodies recovered were probably not strapped in at the onset of the upset.
- Some abnormal 'g' forces were experienced throughout the upset period.
- A major pitch up in heavy turbulence could have resulted in a rapid negative CG shift - unbelted cabin crew and pax thrown toward the rear of the cabin.
- Any ensuing spin/rotation would have introduced forces that prevented cabin crew and pax returning to their seats.
If it were primarily a deep stall with not much rotation, I would expect the 'g' forces to actually be fractionally less than 1g for most occupants.
I tend to think there was 'total suprise and shock' in the cockpit of loss of control (on top of loss of everything else that had already happened). Furthermore there was some understanding that the situation was priority#1, absolutely all effort must be applied to deal with it as quickly as possible, everything and anything else was totally moot until it was resolved.
