"Mr Armstrong spoke it at a rate of 35 milliseconds — ten times too fast for it to be audible."

Who speaks 10 times too fast to be audible? That's just nutty. But I want to believe Neil Armstrong really said “That’s one small step for a man," so I'm glad an Australian computer guy found evidence of the "a." Now, if somebody could figure out some halfway plausible method of establishing the absence of "ein" in President Kennedy's "Ich bin ein Berliner," we could finally be free of the indefinite article problems of the 1960s.
