First Balkan War: Greek aviator Emmanouil Argyropoulos becomes the first pilot to die in the Hellenic Air Force when his plane crashes.

The First Balkan War lasted from October 1912 to May 1913 and involved actions of the Balkan League against the Ottoman Empire. The Balkan states' combined armies overcame the initially numerically inferior and strategically disadvantaged Ottoman armies, achieving rapid success.

Emmanouil Argyropoulos was a Greek pioneer aviator of the early 20th century. Apart from being the first Greek aviator who performed a flight over his homeland, he also became the first casualty of Greek military aviation.

The Hellenic Air Force is the air force of Greece. It is considered to be one of the largest air forces in NATO, and is globally placed 18th out of 139 countries. Under the Kingdom of Greece from 1935 to 1973, it was previously known as the Royal Hellenic Air Force (RHAF).
