The man who opened an emergency door on a jetliner as it was about to land is under arrest in Korea. The 33-year-old man was formally arrested Sunday and charged with violating Korea's aviation security law. He faces up to ten years in prison. He told police he opened the emergency door of the Asiana Airlines Airbus A321 on Friday because he felt suffocated and tried to get off the plane quickly. Twelve other passengers were slightly injured as air blasted through the cabin.
