"He was really an engineer's engineer -- a modest man who was always uncomfortable in his singular role as the first person to set foot on the moon. He understood and appreciated the historic consequences of it and yet was never fully willing to embrace it. He was modest to the point of reclusive. You could call him the J.D. Salinger of the astronaut corps. He was a quiet, engaging, wonderful from the Midwest kind of guy... But when it came to the public exposure that was associated with this amazing accomplishment ... he ran from it. And part of it was he felt as if this was an accomplishment of many thousands of people. And it was. He took the lion's share of the credit and he felt uncomfortable with that."—Miles O'Brien, space and science journalist, speaking on CNN Saturday.
