Explanation: What would it be like to fly free over the seas and clouds of Earth? The first to
experience such an "untethered space walk" were NASA astronauts Bruce McCandless and
Robert Stewart during Space Shuttle mission 41-B in 1984. McCandless, pictured above,

Explanation: At about 100 meters from the cargo bay of the space shuttle
Challenger, Bruce McCandless II was further out than anyone had ever

NASA astronaut Robert Stewart were the first to experience such an
"untethered space walk" during Space Shuttle mission 41-B in 1984.
