The moment Oceangate’s Titan submersible was lost, the support of everyone has come up in the footage recorded on the ship.
Titan gave about 90 minutes in a dynasty to see the Titanic debris in June 2023, killing all five people.
Passengers paid Oceangate to see the ship, which is 3,800 meters below.
The board had Oceangate CEO Stockton Rush, British Explorer Hamish Harding, veteran French divers Paul Henry Nargalat, British-Pakistani businessman Shahzada Dawood and his 19-year-old son Suleman.
The BBC has an unprecedented access to the US Coast Guard (USCG) investigation for the Titanic sub -disaster.
The footage was recently obtained by the USCG and shows Mr. Rush’s wife Wendy Rush, who listens to the transplant voice while looking at the support ship and asks: “What was that blast?”
The video has been presented as evidence of USCG Marine Board of Investigation, which has spent the last two years in view of the frightening failure of all.
The documentary also shows that the carbon fibers used for the construction of submersible began to break down a year ago from a deadly dive.
Titan’s support was with ship sub, while it was diving into the Atlantic Ocean. The video shows Mrs. Rush, who was the director of Oceangate with her husband, sitting in front of a computer, which was used to send and receive text messages from Titan.
When the sub reaches a depth of about 3,300 meters, a noise that looks like a door slamming is heard. Mrs. Rush is seen to stop and then ask members of the other Oceangate crew what the noise was.
Within a few moments, she receives a text message from the sub, which said that it had lost two weight, which seems that he mistakenly seems to have been moving as expected.
USCG says the noise was actually the sound of Titan trapping. However, the text message, which would have been sent just before the up failure, took longer to reach the ship than the sound of the transplant.
All five people died immediately in Titan.
Prior to the deadly dive, Titan’s design was warned by deep marine experts and some pre -ostedic employees. One described it A “hatred” and that the disaster was “unavoidable”,
Titan had never made an independent security evaluation, known as certification, and an important concern was that its hull – the main body of the sub where the passengers were seated – was made of layers of carbon fiber mixed with resin.
USCG says that now the moment has been identified when the hull failed.
Carbon fiber is a highly unusual material for a deep sea submersible as it is incredible under pressure. A known problem is that the layers of carbon fiber may be different, a process called delemination.
The USCG believes that during a dive for the Titanic, the carbon fiber layers of the hull started separating, which took place a year before the disaster – the 80th dive by Titan.
On the board, the passengers listened to a loud bang as the sub made a way to return to the surface. He said that at that time Mr. Rush had said that this noise was a sub -shifting in his frame.
But the USCG says that the data collected from the sensor fitted with Titan shows that the explosion caused the explosion.
“Dive 80 had the beginning of the Dive 80,” said USCG Lieutenant Commander KT Williams.
“And all the people who stepped on Titan after Dive 80 were putting their lives at risk.”
Titan took passengers on three more divers in summer of 2022 – for two Titanic and a nearby rock, before it failed its next deep dive in June 2023.
Businessman Oisin Fanning was on the ship on Titan for the last two dives before the disaster.
“If you are asking a simple question: ‘Will I go again to know what I know now?” – The answer is no, “he told BBC News.
“Many people would not have gone. Many intelligent people who lost their lives, they had all the facts, they would not have made that journey.”
Deep C Explorer Victor Veskovo said that he had serious misconceptions about Titan and told people that divers in the sub was like playing Russian Roule.
“I myself warned people away from going to that submersible. I specifically told them that it was only a matter of time before it failed disastrous. I told myself that I was confident.”
After being vested by the sub, its debris of Mars was discovered across the sea level of Atlantic.
The USCG has described the shifting process through the recovered debris – and said that Mr. Rush’s clothes were found, as well as the business cards and stickers of the Titanic.
At the end of this year, the US Coast Guard will publish a final report of the findings from its investigation, the purpose is to establish what has gone wrong and preventing such a disaster from reworning.
Talking to the BBC’s documentary team, Christine Dawood, who lost her husband Shehzada and son Suleiman in the disaster, said that it had changed her forever.
“I don’t think any person who goes through loss and such trauma can ever be the same,” he said.
Oceangate disaster is likely to continue the waves for years – some private cases have already been filed and criminal prosecution can be followed.
Oceangate told the BBC: “We again express our deep condolences to the families of those who died on June 18, 2023, and all those affected by the tragic accident.
“Ever since the tragedy occurred, Ocenegate permanently reduced its operations and focused on cooperating with its resources completely. It would be unfair to respond further while waiting for the reports of the agencies.”
