From a blog called Fogonazos, Bruce McCandless, floating free in space (1984):
"At about 100 meters from the cargo bay of the space shuttle Challenger, Bruce McCandless II was further out than anyone had ever been before. Guided by a Manned Maneuvering Unit (MMU), astronaut McCandless, pictured below, was floating free in space. McCandless and fellow NASA astronaut Robert Stewart were the first to experience such an "untethered space walk" during Space Shuttle mission 41-B in 1984."
Be sure to click on the photo to see the larger shot; it's breathtaking. Must have been an awesome experience, but jeez, what happens if your jetpack conks out?
