BOAC, he might've or he might've not — that's as open to interpretation as anything. We don't even know if he was around when the captain was explaining the situation to the protocol dude. And when he was in the cockpit for sure, he was busy explaining the mechanics of the aircraft to some other person, and not mentally flying the aircraft. So my guess is that even in the case of his being completely sober, his chances to fully assess the situation and call a halt were only marginally better than a direct intervention from Virgin Mary.
