I lack the screenshots, but..
The B17 bombardier's compartment has been really screwed up since AH3's launch. Just pan around.
The B26's bombardier gauges (to the right of the station) are just for looks. Non-functional. Whilst the B29's (to the left of the station) bombardier gauges DO function. The B17's bombardier gauges DID exist in AH2, but it, oxygen tanks, non existent navigation desk, and even the levers to the left of the bomb sight are really messed up.
That's all I know, as I don't fly some of the other American bombers much.
It's not a huge deal, I guess. The exteriors look great. Now if the interiors could catch up.
Thanks.
