On 9th August 1918, the flight over Vienna took place - a propaganda action by Italian pilots who, during World War I, dropped propaganda leaflets in the districts of Vienna, calling on the Austrians to end the war.

This flight had no military significance, only propaganda, both in Italy and abroad. In addition to the dropped leaflets, the pilot took about 60 aerial photos of Vienna. The inhabitants of the city collected leaflets and their price immediately after the raid was 20 crowns and more. Policemen and soldiers also collected them, and the press reminded them that possessing them was high treason. A few days after the raid, leaflets became more expensive and their price was 100 crowns.
