I was at the Tampa Airshow a couple of weekends back with the Blue Angels and a bunch of other planes and flights. The F-22 Raptor stole the show however, doing things no airplane should ever be able to do in the air. It was truly incredible to watch.
9/11 closed down all the US air shows in our area. There was RAF Mildenhall and RAF Bentwaters which were fairly close by - but at the time I wasn't really doing photography or indeed air shows. Bentwaters is closed now but Mildenhall is still there. I know a guy that often goes up and sits round about there somewhere and takes photos of jets taking off.
Unfortunately the only air show around me is Duxford. I say unfortunately - that's not a bad thing - but it seldom does jets. We did have an F35 show up once. It didn't take off or land at Duxford but it flew around for a bit. Helluva noise!
