Neil Armstrong died this past weekend. First man on the moon. Amazing stuff.
But he is human, and therefore bound to make mistakes. Like the one in his legendary speech. Larrick was kind enough to bring this to my attention this morning.
I found a BBC article from 2009 talking about this lunar mess-up:

Neil Armstrong missed out an “a” and did not say “one small step for a man” when he set foot on the Moon in 1969, a linguistic analysis has confirmed.

The researchers show for the first time that he intended to say “a man” and that the “a” may have been lost because he was under pressure.

They say that although the phrase was not strictly correct, it was poetic.

Yeah, yeah. He messed up. I’ll let it slide given the circumstances.
