There's no real advantage - we currently have autopilot that's quite good, so you really have the best of both worlds - skilled humans plus useful computers. Hi

There's no real advantage - we currently have autopilot that's quite good, so you really have the best of both worlds - skilled humans plus useful computers. Hijacking is not that big a concern, and the cost of human pilots isn't that great (compared to fuel and capital costs). Also, if you centralized things on the ground, you'd create a big target - come get 1000 planes with one hijacking.
