The BBC has reported on a linguistic study that claims to have settled the issue of whether Neil Armstrong said "a man" as part of the first utterance from the moon: he didn't. He did intend the contrast (a small step for one individual man versus a giant leap for mankind as a species), but his speech rhythms show that he didn't pronounce the indefinite article in the first noun phrase. That's the claim. Click here for the BBC link.
