These I the only ones I have, first two from Leuchars 2005, second 4 from Hendon in 2006 (not strictly an airshow but the only other Mustang shots I have). Quality isn't great because they are from my old point and shoot before I got my 400D...
Not really at an airshow per se, but a personal tour at Vintage Wings of Canada. Shot with my point and shoot, before I had my D60, that's why there aren't a ton of closeups.
