naaa, I'm pretty convinced that basic aerobatic and/or stall training is of some basic help even on an airliner. It's just not much helpful if you have a serious instrument failure (for BOAC I'm not saying worst anymore <grin>). In such a configuration you first have to realize that you are in stall, which is not easy at all. But the problem was not that they didn't get out of the stall but that they got in!
