query: When was the Air Force base at Aviano established?
passage: Aviano Air Base
Aviano Air Base was established by the Italian government in 1911, and was used as training base for Italian pilots and construction facility for aircraft parts. During World War I, Italy used the airfield in missions against the Austro-Hungarian and German armies. At that time, two Italian aviators, Captain Maurizio Pagliano and Lieutenant Luigi Gori, conducted an unauthorized, but heroic and successful, air raid on the Austrian naval yards in Pula, in what is now Croatia. In their honor, the base's name was officially changed to Aeroporto Pagliano e Gori, in 1919. During the war the airfield was also overrun by the Austro-German army in the months between November 1917 to November 1918. Between the two wars the airfield was again used as a training base.
