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.

Another terrific episode full of great stories and insights. Having met her, she was a real treasure to the program and remains a treasure to history today. An intelligent, graceful, and beautiful lady. STILL working at Ames! Long may she run! Thanks for this hour. Time well-spent.
