Too bad the old guy was taking his break. Then it would have been a non event. Reocurring icing problems because of the pitot probes seems to be the only problem when the automatics disconnected because of UAS and the PF hauled back for no reason and put it in a deep stall which any airliner would do. Then he held the SS back for several minutes, ignoring the stall warning until impact. Basic flying skills are going away with the new automation. Some were never acquired if a new guy.
