Hi guys, I realise this is not exactly "modelling". however it is awesome reference material.
This short file may be old hat to some of you, but I just came across it and was very impressed!
it is called The German by Nick Ryan. It features a nice dog fight between a Spitfire and BF109 during the Battle of Britain.

Hope you enjoy it as much as I did!
