Jan. 28, 1986, was a crisp, sunny Florida morning. A day filled with hope and pride, and the chance to once more show off American ingenuity and greatness. It was a day filled with expectations, and the big, bright confident smile of a young New Hampshire schoolteacher named Christa McAuliffe. Then, just more than a minute after takeoff, it all grew dark. Millions of people watching on television could hardly believe that a manned space shuttle, something so routine for Americans, could go so horribly wrong in so few seconds.
