To attain a BAC of 0.24%, an average male with a weight similar to the captain's would have to consume approximately 17 to 20 standard drinks over a 12‑hour period. If consumption had taken place over a 4-hour period immediately before reporting for work, a BAC of 0.24% would have required approximately 14 standard drinks.
Insane!
It's a shame that the captain's colleagues knew that he had a drinking problem but no significant action was taken to address it.
And it's shocking that suicide / intentional act is officially a plausible scenario for this crash.
