Helinut - you are right about the Nuclear sites. Though, to be fair, I suspect those zones were more about GA accidently bumping into the buildings than anything else. It made me smile to see that until recently one of the VFR reporting points on the edge of the Lyons zone was the nuclear power station there!
As for getting sammed! I truly don't think so! Jail, maybe.
Max Kenworthy, are you out there? How about some Home Office input?
