Well it says Aerodynamical stall!! I'm sure that includes the Capt stall technic that he use and the fo flap selection.... but fatigue oh noooo nooooo they where properly rested I guess!!! :/ Freaking FAA doesn't want to deal with that can of worms.
Guess what, we still have crewmembers doing transcontinental commutes to rest a few hours in a hotel/crashpad/crewroom and then do a 12 hr duty day. Anything to spend a few more hours at home.
