Interesting. I am told that more accidents are caused by pilots than by equipment failure. Could Chesley Sullenberger have been replaced by AI? If you are the sort of person who believes that a vehicle could safely navigate on our roads without a driver, then I guess that you would say Yes, the Hudson River is an easy choice. Another viewpoint is that the airliner of the future will have a pilot and a dog in the cockpit. The pilot to make a couple of announcements to the self-loading cargo and the dog to bite the pilot if they touch any of the controls.
