1982 Korean Air Force C-123 crash

On February 5, 1982, a Republic of Korea Air Force Fairchild C-123J crashed while on approach to Jeju International Airport, Jeju, South Korea. All 47 passengers and 6 crew were killed in the impact. It remains the fourth-worst accident in South Korean aviation history. The aircraft was engaged in a training mission and encountered bad weather before crashing near to Mount Halla, a dormant volcano.

The 47 soldiers belonged to the army's elite 707th Special Mission Battalion, making the accident the single costliest day in the unit's history.
