Romanian Air Force Day is observed every July 20 in Romania, marked by a spectacular aviation parade over the capital city of Bucharest. This event showcases military aircraft from the Romanian Air Force, the Ministry of Internal Affairs, and the Romanian Intelligence Service, alongside various civilian aircraft. The day honors the history of Romanian military aviation, which began in 1909 with the commissioning of engineer Aurel Vlaicu to construct a powered airplane. The Romanian Air Force was officially established on April 1, 1913, and has since evolved through significant historical events, including both World Wars. The date of the celebration coincides with the feast day of Prophet Elijah, regarded as the patron saint of the Romanian Air Force. This holiday should not be confused with National Aviation Day, which commemorates the first flight of the A. Vlaicu I on June 17.
