That's actually a confirmation bias being missed. Aircraft systems fail and commercial pilots take over and land without mishap all the time. Components inside airplanes, at airports, and even inside air traffic control can and do fail. One example is the attack on the Chicago air traffic control system. Dozens and perhaps even over a hundred aircraft suddenly were flying around with no oversight. Every single pilot took local control, negotiated with the other pilots, and collectively were able to either land or divert without incident.
