I think I suggested...
...that if the fact that two pilots couldn't see what inputs the third was making WAS a factor in this crash, then it shouldn't require two dirty great control yokes to fix it - just a little tell-tale on the instrument panel with a crosshair on it and showing the current 'virtual stick position', as familiar to anybody who has ever played a computer flight sim game using a keyboard instead of a joystick. If the little glowing dot was at the bottom of the circle, everybody would know that 'the stick is being held all the way back', without needing to re-engineer the entire cockpit to stick a big old yoke into their crotch...
