Crash
Korean Air flight 8702 was a scheduled flight from Tokyo, Narita International Airport to Seoul, Gimpo International Airport. Due to poor weather, the crew diverted to Jeju International Airport. Upon landing the aircraft was towed to the main terminal and the passengers temporarily disembarked into the terminal. Two hours later the passengers re-boarded the aircraft for the 1 hour flight back to Seoul
The aircraft took off from Cheju at 21:07 for Seoul. The flight was cleared to land on runway 14R with a crosswind component as the wind was from 220 degrees at 22 knots. Upon touchdown, the captain misused the reverse thrusters in a way the No. 1 engine failed to provide reverse thrust. Coupled with the fact the captain was confused with crosswind conditions and the first officer was preoccupied and not paying attention to the landing, the 747 failed to stop before the end of the runway. The aircraft swerved to the right and slid into a ditch at 50 knots with the fuselage splitting up.
