This area isn't part of the used airfield however it may well be covered by airport laws. Kemble is home to the largest aircraft dismantling company in the country and these are all planes set to be dismantled and scrapped, although it doesn't look like any photos are taken from in the compound rather over the fence.
This is part of the live airport, you can see all types of planes there in the day. There is also plenty of signs saying its against the aviation and maritime security act, or something, to trespass. I think the penalty for breaking into a live airport is pretty stiff. Oh and..... the CCTV is actually live, as I found out the other day.
