@amazeifystore: One reading didn’t match. The crew moved on anyway. During Deepwater Horizon’s negative-pressure test, drill-pipe pressure stayed near 1,400 psi while the kill line read zero. That warning called for investigation, but it was explained away. The test didn’t cause the leak, but the missed signal was a chance to stop the disaster. What should happen when safety readings contradict each other? #DeepwaterHorizon #OilSpill #SafetyLessons #Engineering #RiskManagement #History
