It would be good to have the ability to refuel Aircraft/Rockets at different places around Droo, I would like to be able to take off at Ali base, land at the DSC to refuel and then continue on (example doesn't make sense, but you get what I mean), we should be able to just refuel aircraft to continue the journey.
Maybe it could cost money depending on how much fuel (and which type of fuel) you are putting into the craft. That way, players can't cheat infinite fuel.
