Haven't seen it but assume Spitfires and 109s? I would imagine that in the UK that the various Duxford collections might have been involved.
However, the only pilots I can see in the
IMDB crew list are Dan Friedkin and Craig Hosking.
Dan is well known in the US warbird world and usually appears at Flying Legends at Duxford.
Craig is another American who, some may recall, used to display a Pitts with a second undercarriage unit on the top wing with which he would land and take off inverted.
