I see you have flown with AOA before. If the crew had such a gage in their panel, the accident wouldn't have happened despite the Flight Control System locking out the one good sensor. A normal scan of the panel would have showed the problem with the AOA sensors before they had slowed significantly.
One of the first things taught in U.S. Navy flight training is to not trim into a deliberate stall. Yet, the crew let airplane do exactly that. They had sensor failures but, again, they weren't alert to that. They apparently didn't even know what the stall speed was at their weight and when they approached it, they just kept on going. The AB flight control system can "protect" against some things but clearly not against faulty AOA sensors. The mission of this flight required real thinking pilots but there were none, at least not in the two front seats.
