Armstrong, who died on Saturday at age 82, maintained until the end that there was a lost word in his famous words from the moon.

"I thought about it after landing," he said in a 2011 NASA oral history. "And because we had a lot of other things to do, it was not something that I really concentrated on, but just something that was kind of passing around subliminally or in the background. But it was a pretty simple statement, talking about stepping off something. Why, it wasn't a very complex thing. It was what it was."
