On 12th September, 1918, Lieutenant Frederick Plummer took off from Kenley in an Armstrong Whitworth FK8, (F3453), on a ferry flight to France. He had ascended to 200ft and started to turn, when a gust of wind caught the aircraft and it lost flying speed and nose-dived into the ground, wrecking the machine and killing Frederick instantly.
