If my crew is experienced and at the flakguns, I engage. They've shot down plenty so far. But on the other hand, if it's a patrol in in late '43 or into '44 I crashdive. The enemy AI a/c are just too good and too accurate to do battle with. And to me it's as it should be.
But this is just SHIII without GWX installed. Still working on the 2nd SHIII install for GWX.
