Christa McAuliffe
Challenger Space Shuttle disintegrated in 1986. Just 73 seconds into its flight, the spacecraft broke into pieces over the Atlantic Ocean. The accident temporarily stopped the American space program, and it revamped space travel safety requirements. Killed were Christa McAuliffe (the first teacher in space), Francis Scobee, Gregory Jarvis, Ronald McNair, Michael Smith, Judith Resnick, and Ellison Onizuka.
