‘A world without boundaries’
"You have to dream. We all have to dream. Dreaming is okay. Imagine me teaching from space, all over the world, touching so many people's lives. That's a teacher's dream! I have a vision of the world as a global village, a world without boundaries. Imagine a history teacher making history!"
— Christa Auliffe (born 1948), the Concord (N.H.) High School history teacher who was one of the seven astronauts killed in the breakup of the Challenger space shuttle on Jan. 28, 1986.
