I would love to see an option for AI to return your planes for you.
Say a bomber hits a strat, he can select AI return and up something else, leaving an option for him to get back into the bombers to gun, change course, etc. I think it would increase activity and allow people that dont want to waste their time bombing to be able to bomb and still do something else on the return trip. Would also decrease the need to bomb and bail. If pilot doesn't return you can have AI gunners similar to auto ack or even allow others to join the bomber like manned guns.
