Documentary released audio from Titan sub disaster as one year passes since tragic event

Tuesday (18 June) marks one year since the Titan Submersible went missing in the North Atlantic Ocean.

With 12 months passing since the tragic event, a documentary has released audio picked up by rescue teams during the search.

At the time, the audio gave hope that those onboard the Titan could be alive inside the vessel.

Tragically, however, it was later discovered that the five people on board the sub - which was owned by company OceanGate - had died.

Hamish Harding, Paul-Henri Nargeolet, Shahzada Dawood, Suleman Dawood, and OceanGate CEO Stockton Rush were those on board.

At first, there were hopes that those inside the sub had survived, thanks to a rhythmic banging noise picked up by the Canadian Air Force.

However, in time, the conclusion that the sub had imploded on the day it had gone missing was reached.

As per the Wall Street Journal, the US Navy picked up a noise it thought was the Titan sub's implosion shortly after contact was lost, meaning search and rescue efforts picking up the banging noises were not detecting signs of life.

The audio has since been shared on documentary The Titan Sub Disaster: Minute by Minute, which aired back in March.

Days into the search and the US Coastguard found debris of the submersible, as well as human remains.

However, experts warned not to expect the bodies of the victims to be fully recovered due to the 'unforgiving environment' of the ocean.

Significant amounts of debris have since been recovered, which have been submitted to investigations into the disaster.

Earlier this month, Christine Dawood, the wife of Shahzada and mum to Suleman, commemorated the anniversary of the doomed sub's disappearance and posted pictures of two lit candles.

She also urged others to do something similar if they were missing dear people in their lives.

Writing on Facebook, she said: "When people pass, they take a piece of you with them.

"As the one-year anniversary is coming closer, I'm reflecting back on a time that nearly broke me, and yet the love and support I've received was, and still is, so huge that I can't feel anything but being grateful.

"I miss them every day, every hour, every minute, they will never be replaced. With these candles, I'd like to send their light to anyone who's open enough to receive it.

"I'd like to thank everyone for their love and prayers. I felt them and they helped.

"Light a candle for the missing people in your life and send their light into the world."
