Three years after the implosion that killed five people on their way to the wreck of the Titanic, Canadian authorities have released the final report into the Titan disaster. And if any mystery still surrounded what happened in June 2023, the conclusion is a harsh one: the catastrophe was not caused by an unpredictable event in the depths of the ocean, but by a combination of engineering failures, overconfidence, and a corporate culture that ignored safety warnings.

Spanning 136 pages, the report from the Transportation Safety Board of Canada effectively closes the case. Investigators concluded that OceanGate never verified whether the carbon-fibre hull of the Titan actually possessed the theoretical strength assumed during the design process and that the vessel’s construction and testing failed to follow standard engineering practices.

In other words, the company simply did not know how many trips the submersible could withstand before suffering a structural failure. The implosion occurred during its 88th mission.

Investigators calculated that the hull failed just 5.397 seconds after the crew sent their final message, at a depth of more than 3,000 meters. The last words transmitted from the submersible were simple: “All good.” Seconds later, the vessel ceased to exist.

On board were OceanGate founder Stockton Rush, Titanic expert Paul-Henri Nargeolet, British explorer Hamish Harding, and businessman Shahzada Dawood, accompanied by his 19-year-old son, Suleman.

Over the past several years, various investigations have revealed a long chain of ignored warning signs. Former employees raised safety concerns, engineers pointed to problems uncovered during testing, and experts criticized the company’s decision not to pursue independent certification. According to testimony presented during the U.S. Coast Guard hearings, Rush viewed that process as too slow, too expensive, and an obstacle to innovation.

The Canadian report goes further, arguing that no government agency was truly responsible for connecting the existing information about Titan’s operations. Critical details were scattered across different departments, but no one had a comprehensive understanding of the risks involved. The result was an experimental vessel operating with virtually no meaningful oversight.

One of the investigation’s most intriguing discoveries came from the debris field itself. Among the wreckage was a titanium underwater camera fitted with a sapphire crystal window, specifically designed to withstand extreme depths. Despite the implosion, part of the device survived and, remarkably, its memory card was still functional.

Investigators recovered 12 photographs and nine short videos. But none contained footage from the fatal voyage. The most recent files dated back to May 2023, roughly a month before the accident, and had been recorded during shallow-water training exercises in Canada. The images showed only equipment setup and calibration procedures. No record of Titan’s final moments was ever found.

In retrospect, the absence of those images feels almost symbolic. After three years of speculation, searches, and hearings, what remained documented was not the moment of the disaster itself, but everything that came before it.

If there was once a romantic narrative surrounding the idea of exploring the resting place of the Titanic, the final report leaves behind a much less cinematic and far more human conclusion: Titan was not defeated by the depths of the ocean, but by the limitations of a design that was never fully understood by those who created it.

And perhaps there is an unavoidable irony in all of this. More than a century after the sinking of the Titanic, another tragedy connected to the same site ended with a remarkably similar lesson: excessive faith in technology and the belief that existing rules could be ignored came at a fatal cost.
