Have you experienced the Orbiters ships before? I wouldn't put it past how commonly faulty their technology is that those ships crashed.

[Hell, his own pod made a crash landing from space when he first showed up here. Which was great considering he was already injured before all that shit went down.]

None the less it's an interesting mystery. And it staves off the boredom of being stuck in the middle of a cold as fuck city while the rest of the world is frozen in time.
