Hasan Polatkan Airport — Eskişehir, Turkey

Hasan Polatkan Airport, identified by the code AOE, rests 2,588 feet above sea level in Eskişehir, Turkey, and operates a single runway shared between flight training and scheduled civilian service. The field opened in March 1989 under the name Anadolu Airport, built to give the aviation faculty of what is now Eskişehir Technical University a base for its Flight Training and Air Traffic Control programs, and for years it functioned primarily as a teaching facility rather than a public terminal. Regional air transport for local residents was added gradually as the campus expanded, and in 2017 officials renamed the airport after Hasan Polatkan, a former Turkish finance minister. AOE remains one of only a handful of airports anywhere in the world owned and run by a university rather than a government aviation authority or private operator, a distinction that shapes daily life on its single runway: cadets in training aircraft share circuits with the occasional airliner. That arrangement keeps AOE tightly linked to Eskişehir's identity as a center for aeronautical education in Turkey.
