The B52 is a large aircraft, but it only has a crew of 5 (pilot, co-pilot, weapons systems officer, electronic warfare officer, and navigator). Those are all the same functions a fighter pilot fulfills so with the right electronics setup a single person could technically fly a B52 with full functionality. Could they do it better than a full crew? Probably not. Could they also perform all the in flight maintenance, repairs, reloading, etc.? No, so probably not a good idea. That's why i suggested the npc or offline-friends-as-npc idea (capped at 5 per player). They could continue the fight while you effect repairs or whatever (or vice versa). The B36 would've been a better example with a crew of 13. Then you'd have to join up with at least 2 more players and their crews.
So your logic is "We want multi-crew ships so we're going to limit players to walking OR chewing gum. Not both at the same time!"
I know about the memory wipe. I'm wondering if there was any additional brain damage that would affect people's ability to multitask.
