Experience or focus? Or the experience to know when to be focused?
Both accident crews were negligent in their duties by allowing things to deteriorate to the point of an imminent stall, but that's were the similarities end.
The TLH crew initiated the recovery from an imminent stall correctly and but for the further intervention of the auto thrust, would likely have prevented the stall and successfully executed a go around to try again. The Colgan crew on the other hand, don't seem to have had the 1st clue about how to recognize and recover from an imminent stall.
Just my 0.2c
