Part of it is like riding a bike. Once you learn how to do it, you know how to do it. But part of it is very much not like riding a bike. I love the classroom. I think that's one of the things I love most about it.
Teachers are very well prepared to be astronauts.
Teachers are also skilled at working with complex people in a complex environment. Here, for example, each shuttle mission is an extremely technical and complex challenge. The most important thing to me is doing this for teachers. When Christa McAuliffe was chosen as our teacher in space, it was shortly after A Nation at Risk had been published, and education wasn't faring too well in the public eye. She showed everyone what good teachers were like and brought attention to education in a positive way.
