How would a computer controlled airliner handle something like UAL 232 or QF 32? How would those two have turned out with just a single pilot? What about even relatively minor incidents that require to co-operation of the two pilots?
A survey in large online paper asked if people would fly a self flying airliner. There was a 56% response saying yes. If it every gets down to only 1 pilot up front then I shall be travelling by ship.
