The final, heartbreaking moments of communication between the main crew and their support vessel during the tragedy of the Titan submersible have been revealed through the ongoing investigation.
The U.S. Coast Guard began a set of hearings on Monday, September 16, 2024, to look into the June 2023 implosion of the Titan submersible. This terrible incident killed all five crew members, who were on an expedition to the Titanic wreck site.

One of the most haunting revelations was a brief message sent by the crew to the support ship, Polar Prince. This turned out to be the last piece of communication before the submersible lost contact and later imploded.

The exchange occurred on June 18, 2023, while the submersible was descending to explore the Titanic wreck site. At around 10:00 a.m., the Polar Prince tried to communicate with the crew. They repeatedly asked whether the sub could see the support vessel on its display.
Despite asking the same question seven times in seven minutes, the Titan’s response was sporadic. At 10:14 a.m., the crew sent a short response: “k,” followed by another short reply to the same question: “Yes.” Moments later, they added, “All good here.”

The communication between the two vessels ended abruptly at 10:47 a.m., and the Titan’s final descent ended in disaster. The submersible imploded, killing all on board. The crew included Stockton Rush and Paul Henri Nargeolet. Hamish Harding, Shahzada Dawood, and his 19-year-old son, Suleman, were also on board.
These details were presented with an animated re-enactment during Monday’s hearing. This was part of a larger effort by the Marine Board of Investigation (MBI) to understand what led up to the tragedy and what could have been done differently.

In a press conference held a day before the hearings began, Jason Neubauer, the chair of the MBI, expressed condolences to the families of those lost. He also emphasized the board’s dedication to conducting a thorough investigation of everything gathered in the past 15 months.
According to Neubauer, the board was committed to identifying safety gaps and making recommendations to prevent similar incidents in the future. He also addressed reporters’ questions about the scope of the inquiry. Their ultimate goal is to discover both technical and procedural flaws in the mission.
