What happened
The incident involved a float plane operating out of Killadeas Naval Air Station in Northern Ireland. The aircraft was conducting a training mission over the Atlantic Ocean when it lost contact and subsequently crashed into the sea. The specific sequence of events leading to the impact remains unknown, as no debris or wreckage was ever located during subsequent search efforts.
The flight carried a total of nine crew members from the 131st Operational Training Unit. All individuals on board were lost in the accident. Despite extensive searches, no trace of the aircraft or its personnel was found, resulting in all nine being classified as fatalities.
