The Sea Fury in the Korean War
On 8 August 1952, FAA pilot Lieutenant Peter "Hoagy" Carmichael Royal Navy downed a MiG-15 jet fighter in air-to-air combat, making the Sea Fury one of the few prop-driven fighter aircraft to shoot down a jet-powered fighter.
Indeed, some sources claim a second MiG was downed, although most accounts do not mention this; either way, this is often cited as the only successful engagement by a British pilot in a British aircraft in the entire Korean War.
The engagement occurred when his mixed flight of Sea Furies and Fireflies was engaged by eight MiG-15s, during which one Firefly was badly damaged while the Sea Furies were able to escape unharmed. A similar encounter the next day led to the Sea Fury fighters using their superior manoeuvrability to escape another MiG-15 "bounce" although one Sea Fury had to limp home to Ocean. To enable the Sea Furies to be recognised by friendly forces the aircraft were painted with markings similar to those used during D-Day.
So, not a P51 then!
