190A5's wallow @ 30k.
We had a large formation of B17s hit our base @ T+55 at 30k, with escorts at 30k. C205's and G6's struggle at that alt. Engaging b17 boxes at 30k with them would be suicide. The gun packages are limit, and require multiple passes. Plus there was escort up there.
Maybe if we had K4's, or D9's, and 262's, and 152's.
So yeah, it wasn't much fun. Not to mention the perfect weather conditions that allowed bombing from the alt (no cloud, no wind).
My suggestion to the axis commander would be forget defending for frame 3, just circle the allied fields waiting for vulch oppotunities.
