I hadn't known that this was the source of the Apollo numbering system.:

On January 27, 1967, Apollo 1's crew--Virgil I. "Gus" Grissom, Edward H. White II and Roger B. Chaffee--was killed when a fire erupted in their capsule during testing. Apollo 1 was originally designated AS-204 but following the fire, the astronauts' widows requested that the mission be remembered as Apollo 1 and following missions would be numbered subsequent to the flight that never made it into space.

Wow.

That's lovely.
