In AF447 or QZ8501 all that the crew needed to know was in alternate law you never apply full back stick or to the sides for that matter and the carnage would have been avoided.
All that was needed was an aeroplane that flies the same regardless of what is wrong with it. You mentioned the military, Vilas. They train the way they fight. Having to fly an aeroplane differently because it's systems have had a dummy-spit is not training the way you fight. Throw in autotrim with backstick and you've set the crew up for a big fall.
