The crew of BA038 would have noticed the airspeed decaying below 'Vref' and taken remedial action before stickshaker activation.
In that case why didn't they take remedial action before stickshaker activation in their own 777?
I'm not saying the Turkish crew hadn't a serious lack of monitoring, I'm saying that both aircraft (for different reasons) reached stick shaker at low levels. At that particular point, swapping crews wouldn't have changed much of the outcomes.
A lot of people to mention BA's crew did so admirably well, but no one to elaborate on what they have done better that any other crew. I think most crews would have done the same (disengaging AP at stick shaker and flare what can be flared...). What could non-heroes have done different from that?
