According to many of our non-pilot "experts" on this website, the job is so easy that it would not matter one bit if the operator/pilot was drunk.
According to other "experts", the book should be thrown at him.
Make up your minds.....and remember that the average long-haul pilot landing after a transatlantic flight with no sleep is estimated to think and react at the equivalent of 160 mg/100ml. Just a bit short of the JAL First Officer.
