What makes you believe that a ground pilot will be more competent than the existing air pilots?
It is very rare for crashes to occur because the pilots both become incapacitated. I do remember a crash that occurred because the pilots allowed the cabin to become depressurized and failed to diagnose the problem. Eventually everyone, including the pilots, fell unconscious and the plane circled on autopilot until it ran out of fuel.
