Neil Armstrong's Notebook

In a rare interview three months after the NASA pioneer's death, his brother, Dean, recalled that Neil showed him a written version of the speech months before the Apollo 11 launch, clearly stating, 'that's one small step for a man, one giant leap for mankind.' This runs contrary to Armstrong's own public pronouncements that he decided on the iconic two lines after landing on the moon - but does back up the twin theories that either a) Armstrong flubbed his lines when he lowered himself down the lunar module's ladder or b) static covered the sound of the 'a' as Armstrong maintained. Nonetheless, the hundreds of millions who watched the landings never heard the crucial 'a' in Armstrong's speech, which created decades of debate over whether the first man on the moon actually said what he claims he meant to. - James Nye, The Daily Mail Online
