Well, yeah. I can think of one in specific that I know was sent home, and a few that I've anecdotally heard were. I mean, that's the endgame here, isn't it? I think most of us want to be sent home eventually, and ALASTAIR is trading us time spend in service for transport home, when they've got the extra energy for it.

[He bobs his head, equivocating for the sake of completeness.] Although, conversely, I've heard of people who asked to stay here for good. I suppose this place was better than wherever they called home, one way or another.
