It seems that 'Dunsfold Park' is still in the early stages of site preparation, such as building the access road. Meanwhile the airfield is still operating. But according to the plans, the airfield is soon to be destroyed in favour of 2,600 houses (at the last count). I guess aircraft will be flown out before the end, or left as static exhibits (there's supposed to be an exhibition of the airfield's history) - or maybe even converted into housing?
