Neil Armstrong's famous quote when he took his first step on the moon is "That's one small step for man, one giant leap for mankind"
. However, after returning from space, Armstrong said that he had planned to say "That's one small step for 'a' man"
. Armstrong said that people just didn't hear the "a" in his famous one-liner from the moon
. In a 30th anniversary gathering in 1999, Armstrong acknowledged that he didn't hear himself say it either when he listened to the moon landing
. While it seems no one heard the "a," some research backs Armstrong
. In 2006, a computer analysis of sound waves found evidence that Armstrong said what he said he said
. NASA has also stood by the moonwalker
