Since you're in the UK don't forget the Victory Day Airshow on the 8th & 9th of Sept. Many re-enactors will be there as well as flying and a WWII dance at night.
Unfortunately (or perhaps not - I have mixed feelings about it) I will be in Lake Louise area of Alberta on 8/9 in the middle of a 2 week vacation. Particularly sad because the brand new Albatross and RE8 are flying at Duxford that wekend!
