On This Day In History 01/28/1986, the world watched as the Challenger space shuttle tragically broke apart 73 seconds into its flight. The disaster claimed the lives of all seven crew members, including the first civilian, schoolteacher Christa McAuliffe.
A gripping detail: the launch was initially delayed due to cold temperatures. The investigation later revealed that faulty O-rings were susceptible to the cold, leading to the catastrophe.
This event led to major changes in NASA\'s safety protocols, impacting how future missions were planned and executed.
