We have zillions of Ex WW2 airfields scattered around the country, many with the remains of a runway in place and industrial units scattered around the edges. If I was a planner I would ensue an industrial unit was aircraft sized and that the runway was adequately refurbished for ops but left with "removable" weeds in place.
It would also be sensible to STOP the breaking up of runways (usually for sale as hardcore) whenever a base is sold. Oh, and also stop the army building barrack blocks and fenced vehicle parks on them.
