I think there is a 100% probability that if 100 airliners lost airspeed at 35,000 ft all of them would end up the same way if you pulled full back and held it for over 3 minutes. All pilots but one would have held attitude and power and survived.
One pulled full back and crashed. The others aviated as trained. Seems simple to me. We don't need better automation, we need better pilots. How are the new hires today doing? Can they hand fly or is that not required any more?
