Perhaps because the starship needed for a pilot, someone who wanted to leave, it was choosing loners and/or people who'd been talking a lot about "getting out of this hellhole", and so while some might get reported missing, it wasn't enough to create a sense of mystery and fear?

I figured since we sometimes talk on Wolfma's page, have a few fandoms in common, and got on a big cultural tangent, it would probably make sense for me to friend you. :)
