John Charles Dundas, DFC & Bar (19 August 1915 – 28 November 1940) was a British Second World War fighter pilot and flying ace—a title awarded to a pilot credited with shooting down at least five enemy aircraft in aerial combat. On 28 November 1940 Dundas is believed to have engaged and shot down Helmut Wick, the highest scoring ace of the Luftwaffe at that time, over the English Channel. Wick was never seen again. Moments later Dundas was also shot down into the sea. Like Wick, Dundas was not seen again.
