[Rockin Robbins]

You need to read some Dick O'Kane. One time he was under constant harassment from radar equipped planes. He was spending the night submerged just to get his crew some sleep, and O'Kane NEVER did that. Finally he considered that he was the hunted rather than the hunter and shifted operations to another zone.

So you need to read more. The game is fine with the amount of aircraft. They are dense in certain areas and that's as far as it goes. That's how it was in the war.
