Just to play Devil's Advocate for the moment - how would James have felt if he'd let the matter lie, the Brunei flight had suffered something catastrophic, Nicholls subsequently breath/blood tested and his condition officially judged to be contributory to/the cause?
OK, so James would have kept quiet, as otherwise he'd have been (morally) on a dereliction of duty charge, but who would then have been at fault? Nicholls, the First Officer, James? Perhaps all three?
