The Challenger film documents the Challenger Space Shuttle tragedy, in which the space shuttle broke apart 73 seconds into its flight, killing all seven crew members, including school teacher Christa McAuliffe played by Michelle Williams.
McAuliffe was a New Hampshire high school teacher who was selected to join NASA’s Teacher in Space Project, and had been planning to conduct experiments and teach lessons from the Space Shuttle Challenger. She was posthumously awarded the Congressional Space Medal of Honor in 2004.
