Scott Douglas Jacobsen and Rick Rosner discuss the 2023 Titan sub disaster, highlighting OceanGate’s unsafe design choices, lack of third-party certification, and CEO Stockton Rush’s disregard for safety warnings. Rosner breaks down the physics of extreme deep-sea pressure and why the fibreglass construction was fatally flawed. The conversation contrasts amateur engineering successes like Adam Carolla’s pool project with OceanGate’s catastrophic failure, stressing the importance of rigorous structural testing when human lives are at stake.
