Better be tethered: Jim Newman Back to Astronauts in Hard Hats "It is a challenge, because if you let go of something, it floats away. So you have to be very careful in how you tether. If you let go of the structure, you would float away, so you have to be very careful, make sure your safety tethers are secure."
