"That's one small step for man, one giant leap for mankind."
Neil Armstrong's iconic quote was heard around the world after he stepped on the moon's surface with the Apollo 11 mission on July 20, 1969. But now a new documentary is claiming that Armstrong lied about coming up with the memorable line just before walking onto the moon.
BBC's documentary, "Neil Armstrong – First Man on the Moon" — which aired Sunday — says Armstrong came up with the line months before he went on the mission. Armstrong maintained up until his death that his historic first words on the moon were unplanned.
Armstrong's brother Dean said in the documentary that he thought up the famous statement months before the mission, according to a Daily Mail story . In fact, Dean said his brother handed him a small piece of paper with the legendary and controversial words on while they were playing a game of Risk months before he landed on the moon.
Armstrong spoke the famous words, "That's one small step for man, one giant leap for mankind." Armstrong later insisted that he said "a man" but that the "a" wasn't heard because of static.
"If Neil Armstrong says there was an 'a,' then as far as we're concerned, there was 'a,'" NASA spokesman Michael Cabbage said in the Daily Mail story.
The BBC biopic gives new insights into why the decorated pilot, engineer and astronaut shunned the public glare after returning to the Earth from the moon. Armstrong lived in the Cincinnati area for years and led a quiet life out of the public spotlight as much as possible.
