> Would an input monitoring and control system like on large airplanes have avoided the crash?

Not at all, for example Airbus aircraft "helpfully" average out the inputs. There's a dual input warning, but warnings are weak at preventing accidents.

Some instances where the awful UX around the handling of dual input by aircraft contributed to incidents:

IMO, this is a critical design flaw with all current aircraft that should be addressed ASAP but what do I know :)
