Basically a repair station. I see an earlier suggestion of refueling station being closed by the devs because "the new Restart Here accomplishes this", but actually it doesn't.

What we want is to restore your plane status to the beginning of the session "without resetting the map". If we use the "Restart Here", all map changes (damaged/destroyed ground traffic and buildings, fleet movement, etc) will also be reset, preventing a pretty interesting role play of multiple attack runs from happening.

Right now the actual refuel function the players' been asking about is being achieved by mods (there's one who can refuel you just by typing a command, and another one that actually spawns a refuel truck near you) but it seems that the modders can't go as far as restoring block status (including lost parts and spent ordnance which counts as blocks as well).

We can mark an area and tell the players to stop their planes inside it to get restored, like the hangars in Yeager, Wright and Avalanche airports, the inside space in Ice Base, the docks in Undermountain Base and Water Takeoff, and finally, the hangar (lower) deck of USS Beast (maybe make one for USS Tiny and the Destroyers' flight decks for helicopters to use as well?
