I think it could be cool, I'd have to think of it's roll in this game though. The problem is I don't think anyone would fly it unless rescue operations were implemented. The C-47 does supplies more efficiently considering how far you have to go from base to base to resupply. However, I could see it being useful in resupplying GV's and such.
The problem I see with rescue operations is that people go down so often in such big numbers, there would have to be choppers flying around constantly. I love flying choppers, but I don't think I'd want to do it constantly like would be required.
