AoA vanes keep failing, https://www.heraldnet.com/nation-wor...-had-problems/ Got to handle that in Fault Detection & Isolation software well. Even when 2 AoA vanes freeze up to about the same AoA reading! --> 2014 Lufthansa 1829 - Bilbao.

Looking at several accidents like these Max ones, incidents including Qantas 72 ( https://www.youtube.com/watch?v=H3q5S9PCoJA ), etc., what's needed is an easy, quick, one-button (shielded) way to tell the airplane: Turn off all automatic movements of any aero control surface and throttles. Pilot only, proportional control, direct and quickly done.
There is, usually big and red on the control yoke, called Instinctive Cut Out button, or autopilot disengage button. Trouble is, here is a sub system, that is not routed via the ICO
