Does it have a back window?
TL;DREarly concepts had a rear window by the rescued-crew lifeboat section, and he doesn't remember if it remains but doubts it was removed; the rear-facing tractor beam camera can show the rear.
I'm trying to think if it did. In one of the very early concepts, it did. You have the pilot station at the front, which controls the crew, the tractor beam, and then there's the little lifeboat section in the back where the rescued ship's crew can sit if their ship is unsafe or they just plain don't want to be in a ship being towed through space. They can be in there, and there was a window at the back to look out back over your ship in the early concepts. I do not know off the top of my head whether that's still there, but I don't think it would have been removed. It just wasn't called out in any of the marketing images.
But regardless, the tractor beam camera faces the rear of the ship, so you could use that in a pinch to see behind you if you needed to.
