Narrative:
Fairey Firefly FR.1 PP433: "281/P" of 827 Squadron, HMS Triumph. Substantially damaged 29/8/1950 in a deck landing accident on board HMS Triumph when the carrier was in Japanese waters off Hiroshima, when the arrestor hook failed to lower and aircraft collided with safety barrier. According to an eyewitness report (see link #3):

"An unhappy incident took place on 29th August 1950 when Lt. Cdr MacLachlan, the Commanding Officer of 800 Squadron, became the only aircrew fatality of HMS Triumph's entire Korean tour, as he was mortally injured in a freak accident. He had been in the carrier's operation room inside the Island when a Firefly (believed to be PP433 flown by Lt Bridgeman) crashed into the barrier outside on the deck, and fragments of the propeller flew through an open porthole and struck him as he stood inside. He was later buried at sea with full Military honours; Lt Cdr Handley took over as C.O. of 800 (Seafire) Squadron"
