I'm betting you can't find enough to make even one squadron on either side.
I would imagine you'd have a hard time filling out a flight of Hurricanes, and there are what, 1 or 2 flying 109Es? And zero Battles, I'm sure.
I though it was great, in fact, I have it on DVD. Great flying scenes, great characters (MOGGY!) each a reflection of the different societal and political orientations at work during the period. It covered the technical issues that got the RAF off to a rough start (rigid formations, etc.) and while you might call it a "soap opera," (with dogfighting and killing far more evident than the love scenes) it captured the feel of the times well. And, my wife might actually sit through it.
For another "soap opera" try Danger USB, about a British bomb disposal unit. There's some romance there too, but a hell of a lot of "boffin" detail and people getting blowed up good.
