Capitaine Mathieu Marie Joseph Antoine Tenant de la Tour (5 December 1883 - 17 December 1917) was a World War I flying ace credited with nine aerial victories.
 He went on to score one of the first aerial victories over an observation balloon.
Lieutenant Viktor Georgiyevich Fyodorov (11 November 1885 - 4 March 1922) was a Russian World War I flying ace credited with five aerial victories while flying with the French military air service.
 Having left Russia for Belgium in 1908, with a further move to France, Fyodorov was still living in the latter when World War I began.
 On 21 August 1914, he volunteered for the French Foreign Legion, and served with them until wounded and invalided from infantry service.
 After preliminary duty as a chauffeur, he became a pilot on 27 November 1915.
 After acquiring Pierre Lanero as his mechanic, aerial observer, and gunner, Fyodorov scored three aerial victories in March 1916 with Lanero manning the Caudron's guns.
Captain Konstantin Konstantinovich Vakulovsky (born 28 October 1894, died Summer 1918) was a World War I flying ace credited with six aerial victories.
 A major general's son, he volunteered for aviation duty on 8 August 1914, six days after graduating from university.
 He taught himself to fly, and became one of Russia's first military pilots on 13 June 1915.
 After escaping the fall of the Novogeorgievsk Fortress in a hazardous flight, Vakylovsky flew reconnaissance missions, some through heavy ground fire.
 Given command of the newly formed First Fighter Detachment, he became a flying ace credited with six aerial victories.
 He died in a flying accident during Summer 1918.
Hermann Graf (24 October 1912 – 4 November 1988) was a German "Luftwaffe" World War II fighter ace.
 He served on both the Eastern and Western Fronts.
 He became the first pilot in aviation history to claim 200 aerial victories—that is, 200 aerial combat encounters resulting in the destruction of the enemy aircraft.
 In about 830 combat missions, he claimed a total of 212 aerial victories, almost all of which were achieved on the Eastern Front.
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.
Jola Jobst was a German movie actress who committed suicide in 1952.
 Jobst was married to the World War II fighter pilot, Hermann Graf, from 1944 to 1949.
 Following her divorce she married the actor Wolfgang Kieling in 1950.
Lieutenant Eduard Martynovich Pulpe (22 June 1880 - 2 August 1916) was a World War I flying ace credited with five aerial victories.
 He was a schoolteacher engaged in post-graduate study in France when World War I broke out.
 As he already held a civil pilot's license, he volunteered to serve in French military aviation.
 His 1915 aerial victories were among the first ever recorded.
 After running his score to four, he managed to return home to Russia in May 1916.
 He was assigned to the 10th "Aviatsionniy Otryad Istrebitlei" (Fighter Aviation Detachment).
 After becoming an ace on 1 July 1916, he was killed in action a month later.
 On 2 August 1916, Eduard Pulpe ultimately lost a nearly hour-long air battle against three enemy aircraft.
