See main article: Josef Mai.
Josef Mai (1887-1982) was a German First World War fighter ace credited with 30 confirmed and 15 unconfirmed aerial victories while flying combat for Jagdstaffel 5. While flying for them as a sergeant pilot, he shot down enemy aircraft from August 1917 until war's end. Mai was noted as being one of a trio of high-scoring sergeant pilots called the Golden Triumvirate whose collective victories for Jagdstaffel 5 totaled more than 100; the other two aces were Otto Könnecke and Fritz Rumey.

This list is complete for entries, though obviously not for all details. Background data was abstracted from Above the Lines: The Aces and Fighter Units of the German Air Service, Naval Air Service and Flanders Marine Corps, 1914–1918,, pp. 100–101, and The Aerodrome webpage on Josef Mai http://www.theaerodrome.com/aces/germany/mai.php. Abbreviations were expanded by the editor creating this list.
