List of aviators who became ace in a day

The term "ace in a day" is used to designate a pilot who has shot down five or more aircraft in a single day, based on the usual definition of an "ace" as one with five or more aerial victories.

Ace in a day on two occasions
A Bristol F2B crew – Canadian pilot Captain Alfred Atkey and English observer Lieutenant Charles Gass – became "ace in a day" twice in the same week. On 7 May 1918, they shot down five German planes in a single sortie over Arras. Two days later, on 9 May, they were credited with another five enemy machines in the course of two sorties. Atkey and Gass survived the Great War. Atkey credited with a total of 38 victories, making him the most successful two-seater pilot and Gass with 39 claims was the most successful observer ace of all time.

René Fonck, the top scoring French Aéronautique Militaire and Allied ace of the war, scored six in a day on both 9 May and 26 September 1918.

Ace in a day
The first aviators to ever achieve "ace in a day" were pilot Julius Arigi and observer/gunner Johann Lasi of the Austro-Hungarian air force, on 22 August 1916, when they downed five Italian planes.

The first single pilot (as opposed to double aviators, as is the case with the previously mentioned Arigi and Lasi) was World War I German flying ace Fritz Otto Bernert. Bernert scored five victories within 20 minutes on 24 April 1917. He had a total of 27 kills during the war, even though he wore glasses and had a useless left arm.


 * Andrew Beauchamp-Proctor, the top scoring South African ace of the war, was piloting an SE5a fighter with Royal Air Force No 84 Squadron when he shot down five German aircraft on 19 May 1918.
 * Raymond Collishaw, a Canadian who was the top scoring Royal Naval Air Service ace, piloted a Sopwith Triplane when scoring six Albatros D.V fighters near Menen, 6 July 1917.

 * Eugene Seeley Coler, like W. C. Simon also an American serving in the RAF, at No. 11 Squadron RAF, and also flying a Bristol F.2b, on 13 August 1918 with his observer Cyril William Gladman shot down five Fokker D.VIIs. For this, he was awarded the Distinguished Flying Cross.
 * Heinrich Gontermann of the Luftstreitkräfte achieved five aerial victories on 19 August 1918 when, flying a Fokker D.VII, he shot down a SPAD fighter in the morning and destroyed four Allied observation balloons in the afternoon.
 * Arthur Spurling, a Bermudian pilot of No. 49 Squadron RAF, with his observer Frank Bell, were flying a DH.9 bomber on 23 August 1918, when they single-handedly attacked thirty Fokker D.VII fighters, downing five of them (three by Spurling, two by Bell). Two days later Spurling shot down another D.VII over Mont Notre Dame. The two crewmen shared each other's victories, each attaining ace status in a single mission.
 * Frank Luke of 27th Aero Squadron USAAS, at the controls of a SPAD XIII, achieved five victories on 18 September 1918, destroying two Fokker D.VII fighters, two observation balloons and an Halberstadt reconnaissance plane. Luke was killed in action 11 days later.

Triple-ace in a day
To achieve this a pilot must have destroyed 15 enemy aircraft in a single day. This has been achieved by only five pilots, all from the Luftwaffe:
