Audio from Titan sub disaster that killed five people was released to public ahead of new Netflix documentary

Audio from the horrific Titan sub disaster that killed five people has now been released to the public as a brand-new Netflix documentary about the incident has now been announced.

Back in June 2023, a massive operation was launched after the missing submersible vanished about 435 miles (700km) south of Newfoundland, Canada.

The tiny sub, named the Titan, had an inside space of just 22ft long and 9ft wide with a height of a little over 8ft.

The craft, operated by OceanGate Expeditions, carried five people on board including a pilot and a 'content expert' as well as three paying customers.

Titan lost contact with its surface crew on 18 June, 2023 as it explored the underwater gravesite of the Titanic wreckage, which lies around 12,500ft deep.

The US Coast Guard later announced the 'catastrophic implosion' of the Titan vessel some days later (22 June), after debris was discovered near the wreck of the Titanic off the coast of Newfoundland.

The implosion ended up killing all five passengers on board, who were identified as OceanGate CEO and co-founder Stockton Rush, British billionaire Hamish Harding, French diver/Titanic expert Paul-Henri Nargeolet, and father and son Shahzada and Suleman Dawood.

The 2024 documentary The Titan Sub Disaster: Minute by Minute - which aired on Channel 5 back last March - explained that a rhythmic banging noise was at one point heard during the search, giving some hope that those who were on board might be alive.

These hope-inducing sounds were picked up by the Canadian Air Force every 30 minutes, leading some experts to believe that passengers were signalling for help.

The documentary also informed viewers that the US Navy had picked up another sound around the same time, which they believed to be the submarine's implosion, and implying the banging sounds later heard couldn't have been a sign of life.

Discussion surrounding the devastating audio comes as the US Coast Guard recently shared the last words heard from the crew of the Titan submersible.

The chilling revelation was made on the very first day of what is expected to be a two-week hearing on the causes of the fatal implosion.

According to the life-saving group, the crew on board the Titan sub had been communicating with staff on board their support vessel, named the Polar Prince, by messages prior to losing contact.

It was only after an exchange of repeated inquiries about the submersible's depth and weight as it descended that the final audio was reportedly heard.

After the Polar Prince repeatedly asked if the Titan could still see the ship on its onboard display, the sub informed them they were 'all good here' in a response that was increasingly 'spotty' as the ship descended.

Following the Channel 5 series, a brand-new doc is coming to Netflix later this summer.

It will examine OceanGate CEO Stockton Rush, his quest to become the next billionaire innovator and the 'doomed underwater endeavour that forced the world to reconsider the price of ambition in the depths of the ocean'.
