Fixed it for my tastes. Benson there would have done a much better job.Voyager would have been demonstrably improved with more airlocking. Particularly Janeway in "Year of Hell".

Maybe he's a non-comm, like O'Brien?
Maybe he's actually a full Commander, in charge of Astrography, and just said to himself, "Ya know what? I'm old, we're out in the middle of the nowhere, and I'm never making it home. I'm not in the chain of command, and I don't do away teams. Screw the pips - they're a pain in the butt to put on every morning, and everyone I deal with knows who I am. Janeway can just deal."

Commander McCabe, head of Astrography and best at it in Starfleet. Curmudgeony old coot. I like it.
