You've seen Flying High, yeah
Where the pilot and the self-fly fails (Autopilot).
Well build into Aircraft the means to take control of the aircraft from the air traffic control tower and land the aircraft, where the pilot or the computer is non-functional. Autopilot have stuffed it recently, all three computer systems, in the newest aircraft too, there is a need for an external system.
I was appalled that Autopilot was a box "between" the planes hardware AND the pilot rather than
a V split and a switch , allowing the autopilot OR the pilot to be in control.
Now for those on the ground there is a lesser dimensional problem - self drive errors here are less catastrophic.
