In this article, it says that Today, the U.S. military trains twice as many ground operators for its unmanned aerial vehicles (UAVs) as pilots for its military jets. Its UAVs started off by flying surveillance missions, then took on ground attack; now they are being readied to move cargo and evacuate wounded soldiers. And for commericial flight, automation has helped airlines; what started out as 5 pilots is now done to a pilot and co-pilot.
Do we even need those two? Many aviation experts think not. "A pilotless airliner is going to come; it's just a question of when," said James Albaugh, the president and CEO of Boeing Commercial Airlines...Some problems have to be fixed first, Fully automated planes can't yet visually identify nearby planes, and as for the remotely piloted ones, the civilian variety can't communicate with ground stations, because they haven't got enough bandwidth.
One factor that's often cited for keeping a pilot in charge is what's known as shared fate. That's the reassurance passengers get from knowing that the human in the cockpit wants to live just as much as they do.
So this may be ancient history in a few years.
