If you find a good crashed ship, you can mark the site with a comm ball (an activated base computer should work, too).
If you then post the details here, other people can go there and claim their own copy of the ship. Everybody wins.
The details you need to post are:
The computer you’re using (PC, PS4, XBOX etc);
The mode you’re playing in (Normal, Permadeath, etc);
The galaxy you’re in;
The portal address of the planet the ship is on;
A picture or description of the ship.
Remember - enjoy crashed ships responsibly. When the fun stops, stop.
