What led to the implosion of the sub bound for the Titanic?

Officials have not yet been able to determine a specific reason for why the expedition turned fatal, and investigations into the cause of the implosion are ongoing.

Cameron raised the possibility that the carbon-fiber composite used in the construction of the Titan, which made it lighter than any other sub performing similar dives, may have contributed to its failure.

The material has “no strength in compression,” the filmmaker stated, whose numerous expeditions include a solo dive to Challenger Deep—the deepest point of the Mariana Trench—aboard the 24-foot sub Deepsea Challenger in 2012, told the New York Times. “It’s not what it’s designed for.”

Cameron has now mentioned in several interviews that the deep-submergence engineering community generally adheres to the strictest certifications and safety protocols. He emphasized that this is why no incident like this tragedy had occurred previously.

“We’ve never had an accident like this,” he told the Times. “There have never been fatalities at this kind of depth and certainly no implosions.”
