what did neil armstrong say when he landed on the moon

When Neil Armstrong landed on the moon on July 20, 1969, he famously declared, "Thats one small step for man, one giant leap for mankind". However, there has been some debate over whether Armstrong actually said "man" or "a man." In the official transcript of the Moon landing mission, NASA transcribes the quote as "thats one small step for (a) man". Some researchers have tried to comb the audio files of Armstrongs famous words, with mixed results. Regardless of the exact wording, Armstrongs words have become an iconic symbol of human achievement and exploration.
