Unmanned makes a lot less sense in civilian aviation. The pilots salary is only a few bucks of the ticket price so not much cost saving available. For the combat aviator, you have an american life at risk. Or the could get shot down, punch, and wind up on an AQ YouTube vid getting their head chopped off game of thrones style. Plus, somehow we get away with murder (pun intended) with drones that wouldn't fly with manned sorties.
