Oslo, Aug 18 (IANS): A Latvian co-pilot who admitted to drinking whisky and beer barely hours before an airBaltic flight from Norway to Crete has been jailed for six months, media reported on Tuesday.

A Norwegian court on Monday also sentenced two flight attendants to prison for 45 and 60 days, respectively, BBC reported.

The co-pilot, 38, was found to have a blood alcohol level almost seven times the legal limit. He told the court that he and his colleagues had downed two bottles of whisky before he began drinking beer on August 7.

The reason for their drinking was because they were tired after three consecutive flights.

"We lost control," the man told the court, explaining his blood alcohol reading of 1.35mg of ethanol per ml of blood -- far over the permitted 0.2mg limit.

The crew were tested by Norwegian police after an anonymous tip-off.

The plane's 50-year-old captain is also being held in custody and faces trial on September 17.

The airline said all four had been suspended and it was seeking their dismissal.
