From more than 11,000 applicants to the 1985 Teacher-in-Space program, McCall Elementary School teacher Barbara Morgan was chosen to be the backup to Christa McAuliffe. When McAuliffe was killed in the explosion of the space shuttle Challenger in 1986, Morgan's dream of flying in space was threatened. Using rare footage, as well as interviews with Morgan, her friends, colleagues, students and family, this program shows how Morgan became a full-fledged astronaut, overcoming additional, and sometimes tragic, challenges. On August 8, 2007, Morgan and her crewmates triumphantly launched in the shuttle Endeavour.
