The moment that Neil Armstrong stepped out of the Lunar Module and onto the surface of The Moon is one of the most iconic moments in recent history.
It was "one small step for man, one giant leap for mankind", and the moment was watched by 650 million people worldwide, but it turns out that secret feuds almost ruined the event.
Both Neil Armstrong and Buzz Aldrin wanted to be the first man to set foot on The Moon, and they competed with each other for the accolade, as historian Jim Donovan wrote in his book Shoot For The Moon.
