Although it has been done to death, a stick in the belly of the PNF would have helped...
Yep...just like it helped in the Asiana accident at SFO, and Turkish at Amsterdam, where tactile feedback through the yoke and throttles averted disas...oh wait.
My thoughts (FWIW) - maybe an "Air Marshal" on the jump seat? Or would that be another weak point if it was the Air Marshal that became temporarily unbalanced
Are you joking?
