Wilfrid Reid "Wop" May, OBE, DFC (March 20, 1896 – June 21, 1952), was a Canadian flying ace in the First World War and a leading post-war aviator. He was the final allied pilot to be pursued by Manfred von Richthofen before the German ace was shot down on the Western Front in 1918. After the war, May returned to Canada pioneering the role of a bush pilot while working for Canadian Airways in Northern Alberta and the Northwest Territories.
