Just before i go buy a ship, I have a YT-1210, I can dock vehicles in it, yea sure, fine. My question here is this: if I have the room for it, can I also dock ships? I've noticed two different types of 'docking' symbols. One with the arrow going up, and one going sideways. Is this a designation of what can dock, or simply where (ground,space) one can perform a docking?
