Apollo 50: Apollo VIII, part 1

"There's no question that it was a coffin, and I'd have flown it gladly."
-Frank Borman to Congress, after the Apollo 1 fire

In spaceflight, there are "good" missions and "bad" missions. "Good" missions are the milestones: first man in space, first orbit, first spacewalk, first flight of a new vehicle, first lunar landing, first use of a lunar rover. "Bad" missions are the dull, routine ones: a two-week endurance test, for example, or a repeat flight of the previous mission.

Frank Borman began his NASA career getting bumped from a "good" mission to a "bad" one, and ended it getting bumped from a "bad" mission to a "good" one.
