What Happened in Challenger's Final 73 Seconds?

At 11:38 AM on January 28, 1986, Space Shuttle Challenger lifted off with seven astronauts aboard. For the first moments, everything appeared normal. But 73 seconds later, Challenger was gone. This documentary reconstructs the final 73 seconds of Challenger, following the launch second by second — from the first tiny sign of trouble to the catastrophic breakup. At just 0.678 seconds after liftoff, something had already appeared near the right Solid Rocket Booster. Most people watching that morning could not have known what they were seeing. Then, nearly a minute into the flight, a visible flame appeared. What happened between those two moments? And more importantly… When did the Challenger disaster actually begin? This is the story of the final seconds of Space Shuttle Challenger, STS-51L, the warning signs, the chain of failures, and the decisions surrounding one of NASA's most consequential disasters. Watch until the final seconds — because the most important moment may have happened long before the explosion. Final Minutes — historical events reconstructed through their final moments. #Challenger #SpaceShuttle #NASA #STS51L #FinalMinutes
