Lieutenant Giovanni 'Giannini' Ancillotto (1896–1924) was an Italian World War I flying ace credited with 11 confirmed aerial victories. Rather unusually, he served solely with aviation while he was in the military, beginning in the lowest rank. Among his aerial victories as a fighter pilot were three over enemy observation balloons right after the Battle of Caporetto. As an example of the hazards of balloon busting, on 5 December 1917 Ancillotto returned to base with singed swatches of the third balloon's fabric adhering to his damaged fighter plane.
