Looks good, and I hope to watch the rest of it when I get some time.
Unfortunately you must be careful posting films like this. In the first two and a half minutes the documentary states that Germany was going to invade Britain after they had achieved air superiority AND that Germany lost the Battle of Britain.
This is much too controversial for this forum.
Soon you will start an argument that Germany never, intended to invade Britain AND the Battle never actually finished, Germany just relocated its air forces on the Eastern front! This will rapidly degenerate that it was actually the British who started WWII.
Documentaries like this will be accused of just being a case of the victors rewriting history.
From my brief look at the intro it looks very much like the History I learned at school and have read about in books!
Cheers!
