This is the important trim wheel question in the present context.
Can the trim wheel be used in practice while close to VNE at low altitude, and simultaneously close to full nose down trim while simultaneously the crew are heaving back on the control column for all they are worth?
These are the circumstances in both of the crash cases and there seem to be rumours that under these circumstances the trim wheel cannot be operated by real-life crews. That's going to be a fun airtest.
