Facts about former US astronaut Neil Armstrong:

* Armstrong grew up in Ohio with a strong interest in flight and earned his pilot's licence while still a boy.

* After flying combat missions during the Korean War, he became a test pilot and joined Nasa's astronaut program in 1962.

* As he stepped on the moon's dusty surface, Armstrong said: ""That's one small step for a man, one giant leap for mankind."

* Armstrong's pulse was measured at 150 beats per minute as he guided the lunar lander to the moon's surface, Nasa said. Asked about his experience on the moon, he told CBS: "It's an interesting place to be. I recommend it."

* A crater on the moon is named for Armstrong. It is located about 48 kilometres from the site of the landing.

* In 2005 Armstrong was upset to learn that his barber had sold clippings of his hair to a collector for US$3,000 (Dh11,019). The man who bought the hair refused to return it, saying he was adding it to his collection of locks from Abraham Lincoln, Napoleon, Marilyn Monroe, Albert Einstein and others.

* Despite his taciturn nature, Armstrong once appeared in a television commercial for the US automaker Chrysler. He said he made the ad because of Chrysler's engineering history and his desire to help the company out of financial troubles.
