When I visited Cyprus in 1990, a Cypriot friend and I travelled from Limassol to Nicosia by car, and he kept asking 'could you land an F16 on this bit?' I soon found out why, as there were two stretches of the Nicosia highway laid out with threshold markings, removable crash barriers and parking areas. It was on a later visit I noticed the new section from Larnaca to Limassol also had these attributes, plus the huge roadside signs had massive hinges on them.
Back home, anyone ever wonder why RAF High Wycombe main gate always used to have a couple of 'stubs' with no entry signs at both ends? This was because the bit of road adjacent is nice and straight and was used (so I'm told) during WW2 for things like Austers to land and take off, and these bits of road by the main gate were reserved for parking the aircraft!
