Royally Screwed
This historic and noble airfield has been done for by the nerds at Croydon Council suitably assisted by super nerd JM and 2 FTS who were the planning applicants for the fence.
Anyone with a modicum of gliding experience knows that substantial fences (and signs) on the actual airfield are a hazard and in the case of Kenley have reduced the operational area.
It would not surprise me if someone now decides that the site is too restricted for Cadet training and therefore that would be another excuse to prevent 615 from returning.
