New audio from Titan sub disaster has been released

A new documentary has revealed audio picked up by search and rescue efforts which gave hope that those aboard the Titan submersible could be alive.

Last year, five people died on board a submersible owned by company OceanGate, as it dived down to the wreck of the Titanic.

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

Contact was lost with the vessel on 18 June, prompting a wide ranging search effort.

During the efforts to locate the Titan sub and re-establish contact a rhythmic banging noise was heard, which gave some hope that those who were on board the sub might still be alive.

These banging noises were picked up by the Canadian Air Force and appeared to be coming every 30 minutes, leading some to wonder if the sub's occupants were still inside and attempting to signal for help.

However, experts stressed that they didn't know what the banging noises were, and 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.

Audio of that noise has been heard on new documentary The Titan Sub Disaster: Minute by Minute, which will air on 6 and 7 March on Channel 5 at 9pm.

The documentary intends to follow the details of the Titan's dive down to the wreck of the Titanic and what lessons have been learned from the tragic loss of five lives.

Hours after the oxygen would have run out for the inhabitants of the Titan sub - had the vessel not imploded - the US Coastguard found debris.

Further fragments of the submersible were then discovered, along with some 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.

Following the tragedy, a number of people came forward and said they had concerns about the Titan sub, with some directly urging Stockton Rush to reconsider.

Since the disaster OceanGate's website has said they have 'suspended all exploration and commercial operations'.
