Great pics again Paul, and thanks for that aerial shot.
It's certainly a big field, although perhaps not quite as large as I imagined. The problem here in the UK, especially since the new rules were introduced this year, is space. We have big enough venues, such as Fairford where RIAT is held, but not all of the airfield can be used, and then there's the problem of over-flying the surrounding districts, and the traffic-flow on the ground.
Being a relatively small lump of rock, it doesn't take much to cause a (vehicle) traffic grid-lock, and the airspace is almost as crowded as it was during WW2 !!
Some day, I gotta to get to one of the big shows in the 'States !
