pilotless aircraft with PAX?? Never.
Firstly, the chances of hijacking nav signals are all too real, despite major denial efforts:
Navy: No U.S. drones missing after Iran claim
Second, it would be inhumane to try and get certifications, approvals, legislation changes in multiple jurisdictions, treaties revised let alone figure out how to bloody wel get it done technically.
Third, many airlines have senior captains as members of management and even shareholders, they wouldn't vote for redundancy for sure..
But probably the most important aspect is that no airline will want to be the first to introduce the Boeingbus Aerodrone pilotless airliner simply because people will be wary of it and fly with the human-controlled competition.. I know I would...
we will be using star-trek teleportation before we fly pilotless airlines...
