Sorry to mis-appropriat your thread
I do not know the answer to your question knowing very little about these issues, but would like to bring another tangential issue in. I gather from your post that Bf 109D could operate over Warzaw on september 1. 1939, but many (or most?) couldnīt make it back to base. Previously I thought that only Bf 110 had the range to do it.
So a) what was the effective radius of action of the 109D?, b) was it larger than 109E?, and c) did the Luftwaffe staff misjudge the effective radius of action on the operation you mentioned?
Apologies for the intrusion
