Halli Airport — Jämsä, Finland

Halli Airport (KEV) is located near Jämsä in central Finland and has a notable dual identity: it began as a military airbase and later became a hub for skydiving and general aviation, hosting large international parachuting events due to its long runway and favorable airspace. The airport has also served general aviation, flight training, and occasional charter operations. Its runway, originally built to military specifications, is longer than typical for airports of its traffic size, making it attractive for aviation enthusiasts and skydiving championships. KEV is not a commercial passenger hub but plays a niche role in Finland's aviation and recreational sports scene.
