What makes the "D" special over the B-24 we have now?
it's a slightly faster aircraft, but basically has no ball/nose guns. nose gun was hard to aim that's why they had 3 mg and they would interfere with the bombardier (i think) and the ventral guns were basically useless. earlier models had mostly .303 mg's. there's was lots of modifications to the b24d mostly in the defensive package.
the b24j that we have in the game is just a slower model due to weight added due to a heavier defensive package, along with better navigation, autopilot, turbocharger. in other words in terms of ah it will be the same plane except little faster but hard to shoot with nose & ventral gun.
of course everything is subject to akak corrections
