Botnia,
According to the Swedish-language newspaper you posted, it was an evening flight to Turkey. Either the captain was an absolute alkie to take a drink upon departure, or his yogurt did him in. Usually, in these so-called "drunk pilot" circumstances, the ones who get caught are the early-morning riser pilots who have had one too many the night before and the alcometer still reads positive. It seems strange that this guy had a few in the afternoon or evening just before his flight. I'm glad Finnair is standing behind him and as they say, it would be the first time a Finnair pilot has been connected for alcohol abuse.
