Eerie audio captures OceanGate Titan submarine’s final moments before imploding

The US Coast Guard has released an eerie audio recording that it believes captures the final moments of the Titan submersible before it imploded deep in the Atlantic Ocean in 2023.
The Titan submersible, operated by tourism company OceanGate, was on an expedition to the Titanic wreck when it imploded on June 18, 2023.
The recording was picked up by an acoustic device from the national oceanic and atmospheric administration (NOAA), located around 900 miles from the site of the disaster. It reportedly includes the sub’s “acoustic signature”—the unique sounds it emitted—followed by a sudden, loud bang, which experts suspect was the moment of implosion.

Onboard were five passengers: OceanGate CEO

, British billionaire Hamish Harding, deep-sea explorer Paul-Henri Nargeolet, and Pakistani businessman Shahzada Dawood with his 19-year-old son, Suleman. All five lost their lives in the tragedy, which sparked a large-scale search and rescue effort.
Following the incident, the US coast guard launched an investigation, holding multiple hearings in September last year. Experts, former OceanGate employees, and witnesses provided testimony on the possible causes of the disaster.
The final report on the implosion, which is expected to outline what went wrong, has yet to be released.

Last year, a former contractor revealed that OceanGate's Titan submersible relied on a manually updated Excel spreadsheet for navigation. Speaking at a US Coast Guard hearing, ex-contractor Antonella Wilby criticised the process as “absolutely idiotic,” stating that delays occurred as team members manually recorded and input latitude-longitude data. Former OceanGate engineer Tony Nissen also revealed he refused to participate in a test dive. The Titan lost communication at a depth of 3,346 meters, and used an ultra-short baseline (USBL) system to track its position, but data had to be transcribed from a notebook into a spreadsheet.
