This summer marks 50 years since the first Apollo moon landing. Journalist Charles Fishman's new book 'One Giant Leap' focuses on the untold stories of the ordinary men and women who worked behind-the-scenes on the Apollo missions. "Apollo was the biggest non-military effort in the history of human civilization," Fishman says. He talks about the team at Playtex who designed the spacesuits, the computer programmers, and how NASA nearly forgot to send an American flag into space.
