> Overall, Airbus and its delinked sidesticks was a factor in the accident. Confused, Bonin exclaimed, "[Expletive] I don't have control of the airplane any more now", and two seconds later, "I don't have control of the airplane at all!"[29] Robert responded to this by saying, "controls to the left", and took over control of the aircraft.[73][32] He pushed his side-stick forward to lower the nose and recover from the stall; however, Bonin was still pulling his side-stick back. The inputs cancelled each other out and triggered an audible "dual input" warning. -- So in an Airbus this situation is unambiguous - the plane tells you plain and simple: Both pilots are trying to fly at the same time. With a mechanically linked set of controls, you don't necessarily know whether you're fighting the other pilot or the plane.
