Having PPRuNe'd for a few years and noted with concern the bizarre rostering and inadequate recovery times permitted pilots I can say that I'm far more concerned about fatigue issues in the chaps flying me than a few micrograms of alcohol over already very low limits.
The point that NO commercial accident has been attributable to alcohol for many years is well taken. A disturbing number have however been attributed to fatigue. And what about the pilot who is still upset over the row he had with his GF/wife/neighbour the day before?
This is stupid hysteria akin to that that recently removed a pair of nailclippers from my overnight bag and does nothing to promte flight safety.
