There's plenty of videos around from Oshkosh this year, but this is one of the best. It's taken from the back seat of P-51D Old Crow during a formation and tail-chase with sister ship Gentleman Jim. The only setback is that the producer has seen fit to drown the sound of the Merlins with the theme from Top Gun. Still, if you can grit your teeth for long enough, it's worth a watch.
