The speed limit on UK motorways is 70mph. Many argue that this is wrong. It may be, but if you break the law you get punished. Some argue the drink drive limit is too low, but you still lose your licence.
In this case, a pilot exceeded the limit set by the authority. Some say he REALLY rang the bell on the pissometer. Where is the argument here??? Over the limit, go to jail, go directly to jail, do not collect £200, the end.
Simulator tests have shown alcohol does affect ability, fact.
The question of fatigue is a good one, but you do yourselves zero favours saying that you would rather have a pissed pilot than a fatigued one. NEITHER are acceptable.
He knew the rules and broke them. It is TOTALLY irrelevant that the rules are wrong.
