In November 1918, Rudolf Maister's army confiscated several aircraft. Emil Grizold (in the picture) became the commander of the first airborne squadron in Maribor on November 25. The planes flew over Carinthia and Styria. On March 5, 1919, pilots Grizold and Ludvik Jureš carried with them propaganda leaflets printed in Maribor, propagating the annexation of Prekmurje to the Kingdom of Serbs, Croats and Slovenes. No combat missions were carried out, as the ceasefire of November 13, 1918, prohibited this. The Prekmurje flight almost ended tragically: the plane crashed from a height of 50 meters before reaching the airport, and pilots Grizold and Jureš were injured.
