Security issues !
Most airfields have some form of security and of course a lot of airfields post tresspass notices, afraid I can't comment on public footpaths although I know some have. I was offered a flight at Panshanger which suffers from people crossing the runway, Elstree also has a public right of way accross it's runway.
I can only speak for Sywell. We have suffered in the past with thefts, I understand, from "Pikey's". A complete set of portable fencing was lifted minutes after having been erected ! A lifting barrier was installed but subsequently trashed. The 2 large sliding vehicle gates by Flylight and Sloanes serve a worthy purpose of slowing traffic down coming onto active parts of the airfield. Without those gates traffic would not slow down and could cause an aircraft/vehicle collision. The Sloane gate is open for workers arriving for work and I have seen vehicles not even hesitating to look for taxying aircraft during that time. There is no need for public access at the Flylight gate as there is no parking and no room, it is purely access for the Tower and refuelling point. It is also one of the most active parts of the airfield.
The aircraft owners pay a lot of money for hangarage so they deserve a secure environment, what would happen if something happened to their aircraft ? Who would be to responsible ? I personally think it is a plus that the aerodrome is doing it's best for it's tenants and providing a safe environment for visitors.
As for the airside fence, well it is hardly obstructive ! It is no higher than the one I remember at Sunderland airport when I used to "spot" as a young lad back in the 1970's ! Leavesden was totally inaccessible also in the 1970's. Security at Biggin has increased in recent times. There are lots of airfields that are or have become more secure recently. The main thing here is YOU ASK to look round. It is not a god given right to wander freely around an airfield, most are private property. That is not to say they are unfriendly. A lot are more than happy to let you wander round but it is a matter of courtesy to ask. When on duty in the tower you should be concentrating on aircraft not wondering what some stranger is doing wandering around. As I said before, I have not refused anyone who asks to visit and all the clubs here are extremely helpful and friendly. Just because other airfields don't have security fences, the fact we do at Sywell does not make it a bad thing !
