John "Cat's Eyes" Cunningham CBE, DSO & Two Bars, DFC & Bar, AE (27 July 1917 – 21 July 2002) was a Royal Air Force (RAF) night fighter ace during the Second World War and a test pilot. During the war he was nicknamed "Cat's Eyes" by the British press to explain his successes and to avoid communicating the existence of airborne radar to the enemy.
