Way to go
Yea, I agree with you on the German files. I may have a quick go at them myself, just to fix the dates for traffic appearing in certain areas and reducing the amounts of traffic.
Have you by any chance dug around with the "tactical" options on airbases? I've had no luck with getting recon planes to work, and it would be a kind of a cool feature to have for the American campaign (considering it as a possible replacement for regular contact reports - at least you'd only be able to get a limited amount of them, and only in areas covered by friendly air traffic)...
