And that's the point. You are right Airplanes do actually fly themselves, have done so since the early 2000's I believe Hence its where the term Auto- Pilot was conceived. But yet decades later we still require pilots in these planes..With the recent Boeing planes that had those freak accidents, the technology that was meant to help the pilots fly the planes with ease was actually the reason why they crashed. And those planes had pilots in them. Ports that have gone fully autonomous for container handling have had they're very public issues and they still require human monitoring and maintenance. I do believe automation will come but I seriously doubt it will be in our life time or the next. The technology maybe there but adaptation will have its struggles.once airborne all the pilot has to do is sit there ready to take over the airplane if it gets hit by lightning and the computers reset, however that is exceptionally rare.
