Lieutenant Merrill Samuel Taylor was a Canadian flying ace during World War I.
 He was credited with seven aerial victories while flying a Sopwith Camel fighter for the Royal Naval Air Service, and later, the Royal Air Force.
 He touched off the air battle that resulted in the death of the war's leading ace, Manfred von Richthofen, on 21 April 1918.
 On 2 May 1918, he killed German ace Hans Weiss for his fifth victory.
 Taylor was killed in action by Franz Büchner on 7 July 1918.
Otto Kissenberth (26 February 1893 – 2 August 1919) was a German flying ace of World War I credited with 20 aerial victories.
 He was a prewar mechanical engineer who joined the German air service in 1914.
 After being trained and after serving as a reconnaissance pilot, he became one of the first German fighter pilots, flying with "Kampfeinsitzerkommando" (Combat Single-Seater Command) KEK Einsisheim.
 He scored six victories with this unit as it morphed into a fighter squadron, "Jagdstaffel 16".
 His success brought him command of "Jagdstaffel 23" on 4 August 1917.
 He would run his victory tally to 20, downing his final victim using a captured British Sopwith Camel on 20 May 1918.
 Nine days later, a crash while flying the Camel ended Kissenberth's combat career.
 His injuries were severe enough he was not returned to combat, instead being assigned to command Schleissheim's flying school.
 Although Otto Kissenberth survived the war, he died soon after in a mountaineering accident on 2 August 1919.
Richard Pearman Minifie, (2 February 1898 – 31 March 1969) was an Australian fighter pilot and flying ace of the First World War.

 Accepted for flight training, he completed his instruction in December and joined No. 1 (Naval) Squadron RNAS on the Western Front in January 1917, flying Sopwith Triplanes.
 He went on to score seventeen aerial victories on this type of machine throughout the year, becoming both the youngest Australian flying ace of the First World War and No. 1 (Naval) Squadron's highest-scoring ace on the Triplane.
 The unit re-equipped with the Sopwith Camel late in 1917, with Minifie going on to achieve a further four victories on the aircraft, raising his final tally to a score of twenty-one aircraft shot down.
Wing Commander Edwin Swale {'1': ", '2': ", '3': ", '4': "} (28 June 1899 – 19 July 1978) was an English First World War flying ace credited with 17 aerial victories.

Captain George Edwin Thomson DSO MC (19 September 1897 – 23 May 1918) was a Scottish World War I flying ace credited with 21 aerial victories.
