Quite a bizarre situation where the co-pilot(who apparently had a fair amount of experience and may have been with a training captain) learned to fly after her husband died in a crash at the controls of a plane in the same airline in 2006. The speculation for the ATR crash was that there was a decision to change runways and a stall involved while maneuvering.
Now check out the circumstances for her husband's crash.
