SEOUL - Former vice president of South Korean top flagship carrier Korean Air was sentenced to one year in jail Thursday for violating the aviation safety law in a notorious "nut rage" incident.

Cho Hyun-ah, 41, former vice president of the air carrier and daughter of Chairman Cho Yang-ho, ordered a flight from New York to Incheon, west of the South Korean capital of Seoul, on Dec. 5 last year to return to the gate to expel the head of in-flight service crew after being served macadamia nuts in a bag, not on a plate.

The Seoul Western District Court ruled that she violated the aviation safety law, which stipulates that it is captain who may decide on whether to return to gate for safety reasons or in emergency situations.

The plane moved 17 meters to get the cabin crew chief deplane, resulting in delayed departure for 24 minutes.
