Apparently He had such a high level from drinking the night before not the morning of the flight so unless the night before was like 0200 for an 0600 get up time he must have had a skinful
He must have known he was way over and taking such a flight is inexcusable and will have ruined his career.
Alcoholic or serious temporary problem in his life which caused him to do this ?
Maybe a compulsory breathalyser for pilots on a duty checkin would do more than find those unfit for flight but also make the pilots think twice about trying to get away with it and call in sick
The Japanese trains had a fixed breathalyser at the train driver check in point and took about 40 seconds to do
