Boeing is going to cop a lot of flak over this event but the fact remains that
- The aircraft shouldnt have been dispatched in the first place , and probably wouldnt have been anywhere in the US , Europe or Australia etc.
- Disconnecting both stab. trim motors , as per the check-list , would have stopped the event cold.
-Subsequent Airspeed Disagree events etc. were resolvable by flying attitude and thrust and following the checklist.
Its an analogue aircraft,not fly by wire. Digital add-ons are nice to have,not must have.
Pilots are not backup.
Pilots are the first and last back-stop.
Disconnect and fly the the aircraft.
