About 174 people killed in the deadliest air accident ever in South Korea on today, when an airliner belly-landed and veered off the runway, erupting in a fireball as it slammed into a wall at Muan International Airport. The deadliest air accident on South Korean soil was also the worst involving a South Korean airline in nearly three decades, according to the transport ministry. The two crew members, a man and a woman, rescued from the tail section of the burning plane.
