Cargo airplanes space shuttles (Fearless Blue)

what are these for?
space shuttles are on the intro but no where else
and cargo planes I have no idea what they are for

its a feature simcountry are working on for the near future but its not implimented right now, only the gamemaster has those.

Cargo planes are used to transport supplies from one country to another (such as with disaster relief).

Space shuttles haven't been introduced yet.
