The CCTV photo does not show the Lancashire Aero Club or at least some of it's members in a very good light, LAC members are photographed essentially breaking-in to the airfield for whatever reason.
I'm sure there are two sides to this story but the photo of the rigger-booted group climbing over the fence appear an intimidating bunch, who seemingly weren't invited and had no business being there. If it were my airfield I think I'd be upset too, perhaps an apology might be in order and then leaving the owner of Ashcroft alone so he can get on with running his airfield?
