The Finnish Air Force trains its pilots to land on the road in case of a war in which the airbases are taken out. Not only does it look amazing but they also made a very cool video on it!
A live air operations exercise under the name of Livex-2015 took place between October 5th and 9th 2015 and extended over Finland’s entire territory. Most of this year’s refresher training in the Air Force was merged with the exercise that involved around 1,500 reservists, 800 active duty personnel, and approximately one hundred conscripts.
Finnish Air Force F/A-18 Hornet multirole fighters operated also from a road base in Vieremä.
In the Cold War, highway strips were systematically built on both sides of the Iron Curtain, mostly in the two Germanys, but also in North Korea, Taiwan, Sweden, Finland, Switzerland, Poland, and Czechoslovakia.
Since the Cold War ended most highway airfields have been converted back into normal highways but some have been retained.
