Second Sun

If I'm reading this correctly, the Kootenay exploded while Keating was on it, presumably near enough to Earth to survive and his body wasn't found, rendering him MIA. We might want to investigate the explosion--I doubt anyone unprepared for it can survive an exploding rocket, and Keating may have done that intentionally to fake his death.

We know Keating is here because his neighbors say so.

EDIT: oh it's a boat ship, not a rocket ship. That's much easier to survive without the massive fuel tank sitting next to you. Still worth looking into.
