Grammar in space

Remember Neil Armstrong's famous word, "That's one small step for man, one giant leap for mankind?" Good, that means you don't have Alzheimer's. The quote has been known as the most famous grammatical error since Julius Caesar said, "I came, I am saw, I conquered."

Now an Australian programmer said he found the lost "a" missing in the recording. Making it "for a man." There, problem solved. Now if they could just find the original recording.

Side note: Am I the only one who has always heard the "a" in there?
