Congratulations you have a new ship for free. If you are well geared, this is incredibly easy and you can knock out a ship in a single shot.
You can also just hang around on planets and wait for ships to land nearby. If they aren't Spacers or Ecliptic teams being dropped, you can sneak aboard and fly away. Though I find it kinda lame you can't also take the drop ships used to spawn enemies. Dumb door to go inside is always [inaccessible] :/
Every ship I own I got for free either doing the above, or as a reward for a quest.
