Can anyone describe what functions, if any, you get from the Extra Pack I KC-130 tanker? Is it purely model and animation of fuel probes or is there some (realistic) simulation of the tanker systems (extra tanks, fuel transfer)? It would be great if you can simulate refueling of other planes in multiplayer (without anyone having to "cheat" by invoke the fuel menu), but I'm guessing that such a feature is not included.
