so I don't forget to write 'em out in more detail
Mechanical-
-stuck thruster, terminal spin; slung off the lifeboat w/ crew inside?
-ship stripped by previous crew in-Rings; intact but a husk w/ only hull value?
-loss of power/computer; abandoned ship due to mechanic astrogator incompetence? best for a "rich kid" ship?
Social-
-crew mutiny/fight w/improvised weapons, lack of pay/faction dispute/social issues?
-it's not abandoned- there's a lone survivor; space crazy/staying to maintain a claim on the ship while everyone else left in the lifeboat (pay him off/hire him?)
-Pirate trap: use rep/pay for them to release boarded crewmember or lose them; ship powers up as UIO-affilated?
