Neil Armstrong — "It was a very humbling experience."

"The important achievement of Apollo was demonstrating that humanity is not forever chained to this planet, and our destiny is out in the stars."

"I think the most significant thing we did was to demonstrate that we could do it."

"It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put my thumb over it and I could make the Earth disappear. I didn't feel like a giant. I felt very, very small."

"I was elated, ecstatic, and extremely surprised that we were successful."

"I wasn't chosen to be first. I was just chosen to command that flight. Circumstance put me in that particular role."
