I suspect in twenty years, airliners will have two pilots, but one of them will be at a remote control console, just like UAVs. The one "airborne" pilot will be assisted by the UAV pilot who could land the plane just fine. The USAF is producing a large generation of guys who will fill the positions with lots of experience. The AF is planning on large parts of its operations, even outside of combat vehicles, being unmanned or single-handed.
