Wow what an ugly subject to talk about. Fact is the high stress of the job ranks among others probably in the top 5. It is easy to go out and drink to much and blow a .04 after 8 hours of sleep (the convicted was twice that after the flight). No doubt there are uncounted un documented cases where in these modern times many professional pilots have exceeded these limits on duty. As had been stated this professional heavy drinker was viewed as as competent in his duty despite his BAC level. We do not do this!
What bothers me is that the observant captain did not order him to to not fly as smelling alcohol on his breath pre-flight. I also disagree with the ignorant Judaical system for his criminal sentence. Something along the line of license suspension and rehab would have been sufficient. It would be a black mark on his profession none the less. Alcoholism is a developed disease. It is rare for the inflicted to ask for help due to the repercussions , this is a cultural problem.
