Regarding tyre tracks - they don't have to be aircraft. They could be from any wheeled vehicle.
Re runways - most fighters airfields were grass, no defined runway as such (check out contempory newsreel movies with up to 6 aircraft in line abreast takeoff. Couldn't have been done with tarmac runways!). This permitted takeoff/landing directly into wind. Hence the need for a windsock showing current wind direction. Hope that will be modeled accurately or one could really be in the poo.
