During Shuttle Mission STS118, Canadian astronaut Dave Williams walked in space for nearly nineteen hours. We walk there with him, as Dr. Joe MacInnis accompanies Williams (and all the other astronauts on that mission) in a voyage that very few will ever take.

Astronaut Dave Williams has walked in space a record 3 times, for a total of 17 hours and 47 minutes, longer than any other Canadian who's ever had the privilege of exiting the International Space Station for what the folks at NASA call 'extra-vehicular activity', but what everybody else calls space walking.

Our guide is Dave Williams' good friend Joe MacInnis, a medical doctor and deep-sea explorer who's made a lifelong study of leadership and teamwork in life-threatening environments. During his distinguished career, Joe has worked with teams from the US Navy, the French Government, and the Russian Academy of Sciences. He believes that men and women like Dave Williams are using advanced technologies like extreme-depth submarines and orbiting space stations to create new forms of courage, ingenuity, and collaboration.
