Ironic that members here who blame the MCAS system already are switching to A320s for their flights which also have the same type angle of attack sensors along with software to prevent a stall and have received faulty see also from sensors resulting in a fatal crash before the crew could respond. It was 10 years ago the A320 with 3 sensors had 2 freeze due to maintenance, the software selected those 2 to use neglecting the third working AOA sensor because it differed, put the plane into a stall preventing dive at an altitude from which the crew could not recover before plunging into the Med. darn Boeing copying AB.
