Being assigned to the artillery didn't quash his interest in aviation; his brother was a naval aviator, and Fiala visited airports. While at one, he met
Emil Uzelac, Commander of the fledgling air force of the
Austro-Hungarian Empire. Uzelac arranged Fiala's transfer to Fliegerkompagnie 1 of the
Luftfahrtruppen as a technical officer. Fiala completed training as a flying observer on 28 July 1914, the very day
Austria-Hungary declared war on
Serbia. In November 1914, Fiala took charge of the locomotive of a supply train and drove it to safety even though it was under attack by Russian troops and he was wounded in the action. He was awarded the Silver
Military Merit Medal for this. On 10 November, he also received a most unusual promotion to leutnant (Second Lieutenant) ahead of his sequence in seniority. Although trained as an observer, Fiala's duties in this beginning of the war consisted mainly of arming planes with machine guns, and experimenting with aerial cameras. He also rigged a 30 kilogram (66 pound) radio transmitter in an unarmed plane. It was used in May 1915 on the
Russian Front, during the
Battle of Gorlice-Tarnow: by sending corrections to a receiver on the ground, it successfully adjusted mortar fire. Fiala was briefly attached to the testing section of the air arsenal before being reassigned to a flying unit. ==Aerial Victories==
