I can remember a few years back during gliding competitions that at virtually every briefing, we were told "Don't land at Wescott!" Apart from the security issues (was the hush-hush stuff really tested outside without covers?) there was the real safety issue of hazards in the grassed areas and trees along the former runways. But I know of two people who ignored the instruction. One lost his glider for a week while "special" checks were carried out (more as a form of punishment than anything else) by MOD Police and the other was Christopher Reeve, the actor. His reception was virtually that given to royalty, complete with apologies for not being able to show him more due lack of notice.
As regards arrival procedures from the North to LHR, there was the 'Wescott Snatch" which was a short cut. A certain BA lady F/O caused a slight commotion in the sector controlling this area by asking "Any chance of a quickie at Wescott?"
