Okay, now I think the only way to do this would be a 'Star Citizen' style type interior for b17/b24/lancaster types.
Meaning, basically you can leave your seat and move around to the various stations (gunner spots, radio, nav/bomb).
It's the only way now to do these planes justice, plus it would be the virtual equivilant of a real passenger ride now.
Holy crap, maybe they are really already doing this...
just modeling the Dorsal and belly gun positions would require a lot of work to get correct and right.
Imagine, watching your online squadron or 8 friends all lining up on the tarmac, marching out the the bomber.
Everyone climbing in, posing for screenshots...., then each man goes to his postion and presses the "sit/man" button and then u get a cute animation of him taking his seat or or climbing into the gunner spot.
Infact, now i wish we actually had to walk up to anyplane now and "climb in" lol ala star citizen, i believe
