This incident was used as an illustration of increasing UNMONITORED A/P use, in a series of lectures on Performance and unusual attitude recovery. Excellent material, superbly presented and inarguably pointed out that the failure of the handling pilot to KEEP HIS HANDS ON THE THROTTLES was a primary cause. Had he kept his hands on, he could not have failed to notice the asymmetric movement and (one hopes) taken the necessary remedial action. This lecture lead on to the equally excellent 'Children of the Magenta'. The full series ought to be mandatory viewing for anyone operating in public transport aviation.
