Agree that the number of "superior pilots" that save aircraft are far out weighted by the number that cause accidents (whether from incompetence of fatigue is another question). But one of the biggest hurdles to overcome for the pilotless aircraft will be decision making. How many warnings (unable to find) were there for QF 32. Although computers are faster and getting more so than humans they will continue to digest data to make a “D”. If new data keeps incoming than when will the “D” be made or do we go for a “sensory” overload with the computer reverting back to piloting 101, fly the aircraft, which a) it never did and b) cannot with data incoming.Yes the day will come that computers will fly the aircraft but the Sully example about a computer being quicker only holds water (forgive the pun) if the computer has a program for bird strike, low level, thrust loss from both engines for every possible airport in its programming (and any other scenario not thought of).
