You left out this part, Sky:
Also, most unmanned aircraft systems have a single point of failure for hydraulics, electrical, flight control and satellite link, he noted. "When there's a single point of failure for something that runs into trouble every thousand hours, that's a problem."
What about ditching in the Hudson? Or going outside the normal flight envelope to save the airplane? Or placating the pax in the event of an emergency and restoring order? Seeing and avoiding birds? There will always be some human interaction with commercial airliners, and to remove it from the airplane would be ridiculous.
I agree with hawkesaurus. There may be a slight possibility commercial airliners will pop up, but certainly not any time soon. Definitely not until a mastery of automation can be demonstrated by buses, boats, and trains, and until we can build more accurate computer systems. How many times have the redundant computer systems on the A380, advertised by Airbus to be fail-proof, busted in-flight? Hundreds, if not thousands, of failures can be listed. If you feel comfortable traveling on an unmanned airliner with that kind of safety record, then go ahead.
