Where did you get your information? The German threw everything they could at Britain and almost won on September 7, 1940 when Britain had every functional fighter in the air over the island. Another wave might well have given Germany air dominance which is all they needed. That wave never came.It seems you did not understand my post. The remaining airplans must be spared (together with planes what will be under construction) for the greater goal, the Operation Barbarossa project.
