This would be very cool. Just modify vehicle supplies so that planes can use them too. This way a goon w/ supplies can accompany any big mission and set up a temporary base on a nearby staging island where there's some open area.
This would be a sweet addition to the gameplay. Not only would it be cool on its own merits, but it would also add the requirement of flying patrols around the re-fueling/fixing area while planes were on the ground so that a marauding enemy couldn't just take out 3 guys at once.
