While I'd be the first to agree that EVERY aeroplane should have an AoA indicator (AoA is what wings and therfore flight is all about!) I doubt it would have made any difference in the case of AF447. They had ample cockpit information to fly the aeroplane, particularly attitude information, and they didn't use it.
Concorde did have AoA indicators I guess because AoA is particularly critical on a thin, narrow delta at the high end of the range.
Does / did any other airliner?
