This was on The History Channel a couple of nights ago. I caught the last 20 minutes of it and have ordered the DVD for $25 from the History Channel's website (actually, its part of AandE.com so you can score a boxed set of the Horatio Hornblower movies, too). It mixes color air combat gun camera film with veteran interviews, combat footage, publicity films, and a very good narration. Its just under an hour long. Most of the action is focused on the European theatre with the last 15 minutes about the PTO and Korea.
Hopefully they'll do something similar for the Spitfire, Me-109, and Corsair soon.
