Problem with Blackbushe in terms of major property development - aviation or non-aviation related, is that it has chunks of common land where every man and his dog (or goats) have a right to roam. The general public have a theoretical legal right to roam on registered Yateley Common unit 'CL24', but this right is in fact severely curtailed over practically all of it. If you look at the official website of access land maps you will find that the east-west runway of Blackbushe Airport, the fenced macadamed part of Blackbushe Sunday Market, and the whole of the common owned by the MOD is theoretically excluded. The only parts of Yateley Common CL24 where the public do have a right to roam under CROW are the whole of the Calthorpe part south of Blackbushe Airport and the whole of the 138 acres north of the runways, and possibly the Sunday Market zone (now no longer in operation) unless it is legally part of the airport runways/demise?
Anyway, bottom line is that there are a number oif planning issues and they would have built loads more hangars and other infrastructure etc. years ago were it not for the hassle involved on the planning front.
