Job: Cargo transport pilot

The same idea as below can also be used for cargo boat transport. Job spawn is at the airfield.

Have a bunch of cars at the airfield and one cargoplane. When you drive a car into the loading zone and hold F, the server will know it's "checked in". Then fly all checked-in cars to the dirt runway using the cargoplane, and hold F in the unload zone there to "check out" with each car. Obviously, only cars that have been checked in can check out. For each transported car you get 300xp and $150.

At the dirt runway, there will also be cars that you can check in there and fly back to the airfield. Both runways also need like two acrobat planes to fly back to the main island, and maybe it's a good idea to give the airfield its own snackbar too.
