They also only used data from a SINGLE sensor for a safety critical system, which is a cardinal sin in aviation. The plane already has two angle of attack sensors, you couldn’t write a few more lines of code to have it use both of them? Not only did they not do that, they even went so far as to make the alarm that warns when the sensors are mismatched a paid option. They wanted airlines to fucking pay extra for the privilege of knowing when something on their plane isn’t working properly.
