The Finnish Air Force completed Baana 16, a military exercise where they practiced launching F-18 Hornets and BAE Systems Hawk trainer planes off of highways. The exercise was completed in October of last year.
The videos show F-18 Hornets, BAe Hawks, Saab Gripens and a CN-295 smoothly launching off the highways and even landing with improvised arresting gear.
In a war situation, when airfields make attractive targets for enemy missiles and airstrikes, having the capability to launch from unconventional, unexpected places becomes a huge asset.
Sweden also participated in the exercise using their domestically built Saab Gripen jets, according the a Finnish release.
