Better be tethered: Mike Gernhardt Back to Astronauts in Hard Hats "One of the things that you learn to do, in addition to processing the task that you're working on and thinking two or three steps ahead, you're also constantly thinking about where your tether is, where your buddy is, where his tether is, and where the airlock is. So that in any point in time, if something should go wrong, if he should get a leak in his suit, I know where he is, and I'm going over there, and I'm going to help him get back to the airlock."
