From NPR:
John Young, who was one of NASA's most experienced astronauts and the first to fly in space six times, including a moon landing, died on Friday after complications from pneumonia. He was 87.
In NASA's history, few astronauts were more accomplished than John Young. His career was filled with firsts: he was the first to fly in space six times. He was on the first Gemini mission and he commanded the first shuttle flight. (He was also one of 12 people to walk on the moon.)
"If anybody deserves the title of legend it would be John Young," said Andrew Chaikin, an author who has written extensively on NASA.
