I'd have to say the best part of this film was the F4U formation with the camera shot at the end of the film.
You still have some more work to do on the sound effects, the sound of the bullets striking the other plane didn't match with the visual details. Some more camera shots would be nice, yet you can't please us all the time.

Thanks for zooming in, but not too far. This is something lots of film makers miss. I managed to see the action and what was happening. That's what's important.
Nicely done.
