The Challenger disaster wasn’t caused by an O-ring “exploding.” 🚀 Cold temperatures made the rubber seals less responsive, allowing hot gas to leak through the booster joint. That blow-by damaged critical hardware, and 73 seconds after liftoff, the external tank ruptured. The deeper lesson? Warnings don’t protect anyone when decision-makers normalize unacceptable risk. What do you think was the biggest failure: the design, the communication, or the launch decision? #SpaceHistory #ChallengerDisaster #NASAHistory #EngineeringFailure #EngineeringLessons #RiskManagement #AerospaceEngineering #ScienceExplained #HistoryTok #LearnOnTikTok - @amazeifystore
