Fault
Opherphen, obviously you're right that pilot performance is involved. And the pilots of AF447 might have made mistakes. But I'm not sure, whether it will be useful to blame the pilots even if they did make mistakes. As I'm sure you realize, a serious look has to be taken at WHY they made any mistakes that they made. We might never know why they didn't divert from the weather, but maybe we can guess. And if indeed they didn't realize they were stalled, WHY didn't they realize they were stalled?
