RoyHudd -- Surely these are two different issues? Hand-flying skills and instrumentation. From the published CVR evidence the pilots did not know for sure what the aircraft was doing. Something like "but the airspeed is mad, no?" from the PF. The instruments have to work and the pilots need to have training and experience. Neither by itself would have saved the aircraft, it seems....back to the classic "accidents are almost invariably due to a chain of events, not a single cause".
