Single pilot ops is even less likely.
How would a pilot accumulate enough experience to command an aircraft safely, if the "master and apprentice" system of two pilots is abolished? 200 hour wonders in sole charge of an airliner?
And if he just sits there monitoring, not doing anything until it goes wrong, how will he keep up his perishable handling skills?
And as for remote pilots on the ground - the main conclusions from the Sioux City crash was the need to keep pilots on board. The three pilots on board got the virtually uncontrollable aircraft to a survivable position. Every other pilot in the company was put through the same scenario in the sim, and couldn't replicate it. The conclusion drawn was a pilot will do better if his ass is on board.
