Plane crash tests South Korea's acting president two days into role

When South Korea's acting President Choi Sang-mok arrived at the scene of the deadliest air disaster on the country's soil on Sunday (December 29), he had been on the job for less than 48 hours, replacing two impeachments. The bewildering turnover left the government scrambling when a Jeju Air flight slammed into a wall at Muan International Airport, killing most of the 181 people on board. Kristy Kilburn reports.
