Didn't the pilots know they were falling from the sky, for what, a few minutes? And didn't the freaking stall warning sound a few times? AF447 is an amazing case study of WTF.You don't do stall training in commercial aircraft. The simulator training programs get hammered by the NTSB with every significant incident.
Seriously - the guys flying AF447 made a stunning sequence of errors. Their inability to recognize what was happening to the aircraft is a pristine indictment of their training. All the basic indications of airframe stall were right there in the cockpit with them. They rode that thing into the ocean.
