    I totally enjoyed hearing this interview. There are many references to the astronaut's nurse in space history, and to hear her voice tell her part of the story was amazing. I loved hearing the development of her position, her characterizations of the astronauts - her personal stories of a great time. As a child during that period, I became fascinated by the space missions, and like many, the astronauts were my hero's.
