I have a question, Apparently the AoA sensor is switched from right to left and left to right on successive flights of the Max 8. But in the case of the Lion crash the aircraft experienced problems with the working AoA on the preceding flight and after landing this AoA was replaced. But on the next flight i would expect the opposite AoA to be used. Thus it appears two AoA sensors were malfunctioning. This seems deeper than simply a single AoA. What am i missing.
