Only a question, but who can tell me, how many airline accidents have been CAUSED by drunken pilots?
More to the point, how many have been caused by pilots with 0.2 or 0.4 pro mill readings?
Fatigue is a FAR more significant factor than these levels of alcohol.
But of course politicians don't tighten the rules regarding fatigue, they slacken them. Fatigue is not easily tested, nor smelled on the breath, and airlines seem to want ever more work from fewer and fewer pilots!
Let's get these issues in perspective!
