I'm looking down at the Earth right now and it's 250 miles below me, and only a small portion of that is the atmosphere, and when that Soyuz hits that atmosphere going 17,500 miles an hour, a lot of things have to happen just right to make sure we touch down and parachute safely. So when you look at that big space between us and the speed involved, it's pretty serious. And it's something that you definitely think about and consider. But it's my second time flying the Soyuz, my fourth time flying in space. It's something I signed up to do, and we'll be ready for it next Tuesday.
