The photos I have seen from Midway, where the B-17s failed to get a single hit on the Japanese CVs, the Japanese CVs are all turning and maneuvering hard. None of those Japanese captains was thinking "Oh, level bombers, those can't hit us."
Now, I agree it is easier in AH to hit a ship going straight than it was in reality, but a bomber at 20k will almost never hit a maneuvering ship.
