What happened
During a nighttime transit from Iwakica to Suwon, the crew of a Douglas AD-4B Skyraider experienced a mechanical emergency involving an engine failure. After notifying ground controllers of the situation, the flight crew decided to perform a ditching maneuver. The aircraft went down during this phase of flight, and the wreckage was located by search teams two days after the disappearance.
All ten individuals on board, consisting entirely of the crew, were killed in the accident.
Findings
While official investigations concluded that the primary reason for the crash was an engine failure, there has been speculation regarding external factors. Some theories suggest the possibility that the aircraft may have been struck by a US Navy Douglas AD-4B Skyraider during a night patrol, though this remains unconfirmed.
