A Japan Airlines pilot was jailed for 10 months on Thursday after being caught 10 times over the alcohol limit shortly before take-off from London Heathrow Airport.
First officer Katsutoshi Jitsukawa, 42, was sentenced at Isleworth Crown Court in west London.
The Japanese co-pilot was arrested at Heathrow on October 28 after failing a breath test 50 minutes before the Japan Airlines flight JL44 to Tokyo was due to take off with him in the cockpit.
"You are an experienced pilot but you had clearly been drinking for a long period up to a time shortly before you were due to go into that plane," said judge Philip Matthews.
"Most important is the safety of all persons on board that very long-haul flight, potentially 12 hours or more. Their safety was put at risk by your inebriation and drunkenness.
"The prospect of you taking over control of that aircraft is too appalling to contemplate. The potential consequences for those on board was catastrophic."
