how about...a new supply crate for aircraft is added to the game? it would be very useful, run out of fuel when u got 6+ kills to your name? land your plane the best u can, then have a friend fly out a c47 and drop some AC(aircraft) sups to u, the sups would only resup your fuel, not ammo.
plus gv transports can carry this, therefore planes can land at the gv bases, then m3s come out and deliver the supps. but supps would also have the "30 secs" wait period.
