If you examine the famous line uttered by Neil Armstrong in 1969, you realize it doesn't really make sense. Because "man" and "mankind" essentially meant the same thing, if his famous line was accurate, what he basically said was, "that's one small step for mankind, one giant leap for mankind."

Upon returning home, Armstrong clarified that he did say "one small step for a man," which makes much more sense. Peter Shann Ford, a computer programmer, said he found proof that the missing "a" was actually just lost in transmission back to Earth.
