Tickets go on sale on 12 June. It's not expensive (£8pp), so I might make the trip to see if there is anything exciting on show.
Ive done this twice and really enjoyed it, the guys who bring full cockpits with them, actually let you have a go, which is nice and you get a bag full of goodies i usually stay on camp the night before as its right next door. Nice and handy!
