Who was the most famous air ace in the RCAF?

Billy Bishop stands out as the most famous air ace in the Royal Canadian Air Force (RCAF). During World War I, he gained renown for his exceptional skills as a pilot and his impressive number of aerial victories, which amounted to 72. His bravery and tactical prowess made him a significant figure in Canadian military history and he was awarded the Victoria Cross, Canada's highest military honor, for his acts of valor.

Bishop's legacy continues to resonate as he is often celebrated as a symbol of Canadian heroism in the air, contrasting sharply with the profiles of other figures in the provided options. Sir Douglas Haig was a British Army officer known for his role in leading forces on the Western Front, not an air ace. Gordon Lightfoot is a well-known Canadian folk musician, not associated with military aviation. Alfred von Schlieffen was a German general known for the Schlieffen Plan in World War I, but he did not serve as an air ace. Thus, Bishop's achievements in aviation during the war solidify his status as the most iconic air ace in the RCAF.
