Great screenshot Johan. Finally we see the air combat sim at work, and it looks great!
I have some theories here, so let´s go:
The bar to the left is probably what you see when you click on the airplane on the top, a list of all your air groups (nice addition, by the way). The provinces listed are the ones that have airports (probably planes can only rebase to said provinces) and the numbers represent some sort of size and/or quality of airfields. The number before the bar seems to represent the actual capacity of the airfields and the number following the bar would represent the total capacity. If this is true, it means that you can damage the airfields. This adds a hell lot of possibilities (and fun!) to the Battle of Britain. I can already see my stukas tearing apart the airfields of those nasty Spitfires instead of bombing the hell out of London.
Also, for what I see, the number in the province does not represent the maximum number of air divisions a province can take, since the Dover province (which is rated at 5/5) apparently has 14 air groups (7+5+1+1).
I coul also stress the conclusions of some other people. Apparently the Doctrines will play a big part on the coices you´ve got for your air missions. I also have a question: is the "Interdiction" mission given to the 11th Group an order to support the ground troops? A la blitzkrieg-style of combined-arms warfare?
All in all, it looks sweet. Thanks Johan!
