Sorry, I didn't mean to insinuate that anyone here had busted displays or that anyone here deserved it as an individual; it just seems to me that the reasoning behind the extended buffer zone may stem from the actions of a few in the past.
I honestly can't see it presenting a problem though, there'll be a controlling authority for the airspace, if you have a dire need to be within 5nm of Abingdon during the few hours of display practices on the previous two days then ask and, if it's not needed for safety, then I'm sure they'll sort something out.
They wouldn't have asked for the RA(T) if they didn't feel they needed it.
It's a few hours on a couple of days to protect those practicing and then a bit longer on the day itself. I don't get why it's a big deal.
