Many on here do not appreciate all the Warnings & associated noise a modern airliner can throw at you. The systems are not really designed for multiple failures. Trying to see a trim wheel stop starting whilst un-reliable airspeed with all the minor failures that are being caused by the primary cause takes great airmanship. Just demonstrating a MCAS failure on its own is imho irrelevant. Hopefully Boeing will take multiple failures into consideration when re-certifying the Max, but I will not be holding my breath.
