I don't remember what the film was called. It was posted here a year or so ago, and I really liked it.
It's from another game. It starts with B17s starting up engine by engine, they lift and fly out there, guns blazing. They bob a target while 109s fly around and through them, and then there's one of the scrolling text stories about who the pilots were and what real-life squadron it was meant to honor.
Any ideas?
