For delivering non-critical goods, pilot-less drones will doubtless turn out to be mostly okay.  Not so much with people on board I think.  Why do I already know how this "pilotless airliner" thing will go?  The airlines and aircraft maker will swear up down and sideways how safe they are, how they've flown X-million of accident free miles, etc. and how much better these are because reasons. Meanwhile the airlines can't fly me from one city to another without losing my luggage half the time.  Do they really expect me to trust them to handle pilot-less aircraft right?  I will not fly on -ANY- unmanned (unpersoned?) aircraft, just so the cheap-skate airlines don't have to pay for pilots!
