Former NASA flight director Eugene "Gene" Kranz, author of "Tough and Competent," shares stories from his 34 years at NASA's Mission Control, beginning in 1960 with his work on Project Mercury, the first American human spaceflight program. He was later flight director for NASA's Gemini and Apollo programs, including the 1969 Apollo 11 mission that landed Americans on the moon and the 1970 Apollo 13 mission that almost ended in tragedy ("Houston, we've had a problem…" reported Commander Jim Lovell in route to the moon). Mr. Kranz, who turned 92 this year, also talks about his work on Skylab and the Space Shuttle Program, and weighs in on NASA's current plans to send humans back to the moon.
