Eileen Collins is the first woman ever chosen to be a spaceship pilot. She is also the first woman to command(指挥) a spaceship. Today she has flown more than 5, 000 hours in more than 30 kinds of airplanes.
   Talking about high school, she said, “I began reading all kinds of books about famous women pilots. These women went and flew into dangerous places. Their stories encouraged me.” In 1977 Eileen got a pilot’s license and the following year she graduated from university. She went into space in 1999 at the age of 43. She took with her the hopes and dreams of a nation of young people on the earth.
   Eileen is not only an astronaut but also a wife and the mother of a young daughter. She has short curly hair and friendly brown eyes. She met her husband, Pat, while they were together in the air force(空军).
   When she was named as the First Woman Spaceship Commander in 1998, Eileen smiled and said, “When I was a child, I dreamed about space. It was only a dream that I would be one of the astronauts someday. I hope all children will be encouraged to reach for their dreams, when they see I go into space. I believe dreams do come true!”
