Actress Lucy Liu was left terrified during a recent flight when a drunk man charged down the plane towards the cockpit. Liu was returning to the U.S. from Cote d'Ivoire in Africa, where the United Nations Children's Fund (Unicef) ambassador witnessed the threat to child survival caused by a lack of clean drinking water - when the incident took place. The Kill Bill star was drifting off to sleep when she was awoken by the sound of people running, followed by a midair brawl. She recalls, "We took a night flight from Africa back. In the middle of the flight back - everyone's asleep - all of a sudden you hear... people running down the aisle. Somebody had run from the coach class, and apparently had had too much to drink, and was tackled. "You couldn't see anything because it was totally dark and they were behind the curtain (dividing partitions of the plane). And you see just arms and legs and screaming. There were six stewards that had to take down this guy. "It was terrifying because you don't know what's going on.."
