Ground Control to Major Tom.
Tobbs had the line "It's time to leave the airlock if you dare" stuck in his head, which he knew probably weren't the right words. (PROSE: The Hungry Night)
Behind the scenes Edit
In the real world, "Space Oddity" was written and performed by David Bowie. The title of the song is not named in either story, but can be inferred from the context.
The comic story The Hyperion Empire refers to Chris Hadfield's "singing astronaut schtick", a reference to Hadfield's cover of "Space Oddity".
