the idea is you can find a ship or take one from someone in a non safe zone, and once you bring it back to a station as you enter the station it will become yours. a couple months ago it wasn't working yet, when i would fly another person's ship back to a base or whoever abandoned those ships it would lock up on me and fly on its own back out of the station are. i do not know if they made it where you can register other peoples ship to you or not, but a ship in a non safe zone was flyable at least.
