Description
A highway strip, road runway, or road base is a section of highway, motorway (autobahn), or other form of public road that is specially built to act as a runway for (mostly) military aircraft and to serve as an auxiliary military air base. These runways allow military aircraft to continue operating even if their primary air bases, which are vulnerable targets in wartime, are rendered unusable.
