@ChristiaanJ - I'm not talking about "on the edge" training in sims for line flight crew, I'm talking about basic manual handling - turns, pitch management, stall warning recoveries and the requisite amount of sidestick manipulation for each.
If the PF had apparently lost control because of external forces beyond his ken, then you'd be right, and there wouldn't be much that more training could accomplish. But to all intents and purposes it looks like this guy controlled a perfectly flyable airliner (albeit with minor systems degradation) into a full stall -which he neither recognised nor was able to recover from - by significantly overcontrolling at altitude.
Someone needs to tell the "beancounters" just how expensive crashes can be, not to mention the amount of business they stand to lose when it turns out that their training regime produced a fully-qualified pilot who ended up completely out of his depth making basic course corrections at altitude!
