Captain Henry Meintjes (25 December 1892 – ??)
 was a World War I flying ace credited with eight aerial victories.
 He participated in Albert Ball's final dogfight, during which he was wounded in the wrist.
Kurt Welter (25 February 1916 – 7 March 1949) was a German "Luftwaffe" fighter ace and the most successful "Jet Expert" of World War II.
 A flying ace or fighter ace is a military aviator credited with shooting down five or more enemy aircraft during aerial combat.
 He claimed a total of 63 aerial victories—that is, 63 aerial combat encounters resulting in the destruction of the enemy aircraft—achieved in 93 combat missions.
 He recorded 56 victories at night, including 33 Mosquitos, and scored more aerial victories from a jet fighter aircraft than anyone else in World War II and possibly in aviation history.
 However this score is a matter of controversy; research of Royal Air Force losses suggests Welter overclaimed Mosquito victories considerably.
