A UK billionaire, French submersible pilot and the CEO of a company that provides crewed submersibles are believed to be three of the people on board a missing vessel.
A search remains ongoing. But rescuers fear that the submersible, named the Titan, may have no more than a couple of days at best before its life support systems fail.
Five people were onboard the submersible at the time it lost contact, according to the US Coast Guard.
Sky News also understands that French submersible pilot, Paul-Henry Nargeolet, and chief executive and founder of OceanGate Expeditions, Stockton Rush, were also on board.

Where and where did the submersible go missing?
The submersible went missing on Sunday in the Atlantic, some 435 miles (700km) south of Newfoundland, Canada.

The Titan was launched as part of an expedition involving an icebreaker, The Polar Prince, that was hired by OceanGate and formerly operated by the Canadian Coast Guard.
The Polar Prince is now being used to search the surface near to where the submersible was launched.
It is understood from the vessel’s operator that Titan has a 96-hour oxygen supply in case of emergencies meaning only around two days of “life support” remain.
The US Coast Guard Northeast said The Polar Prince and the 106th Rescue Wing would continue surface searches throughout Monday evening.
What is the Titan?
The Titan is a small submersible operated by OceanGate – a US-based company which offers crewed submersibles for industry, research and exploration.
Tickets cost $250,000 (£195,000) for an eight-day trip including dives to the wreck.
According to the company, the Titan is capable of diving 13,120ft “with a comfortable safety margin”.
It takes the craft around two hours to descend approximately 12,500ft – where the Titanic wreck lies in a trench in the Atlantic.
The vessel, which weighs around 23,000lbs (10,432kg), operates by pinging back a message every 15 minutes to signal to those ashore that it is safe.
However, Sky News understands that those pings have stopped.
In a May 2021 court filing, OceanGate said the Titan had an “unparalleled safety feature” that assesses the integrity of the hull throughout every dive.
At the time of the filing, Titan had undergone more than 50 test dives, including to the equivalent depth of the Titanic, the company said.
During its 2022 expedition, OceanGate reported that the submersible had a battery issue on its first dive and had to be manually attached to its lifting platform, according to a November court filing.
What do we know about the three passengers so far?
Mr Harding is the current Chairman of Action Aviation – a sales and operations company that offers a range of services in the business aviation industry.
Posting on social media on Sunday, Mr Harding confirmed that he was joining OceanGate Expeditions – the company that supplied the vessel – as a mission specialist.
He wrote that due to bad weather in Newfoundland, Canada, the expedition was likely to be the first and only manned mission to the Titanic in 2023.
Based in the United Arab Emirates – where Action Aviation headquarters is – Mr Harding described himself on social media as a world explorer.
He holds the Guinness world record for the fastest circumnavigation of the Earth via the North and South Poles by an aircraft – 46 hours, 40 minutes and 22 seconds.
Last year he also took part in the fifth human space flight by Blue Origin – an American aerospace company founded by Jeff Bezos.

OceanGate CEO speaks to Sky News
Stockton Rush is CEO and founder of OceanGate Inc – a company that provides crewed submersible services to enable researchers and explorers to access the oceans’ vast resources.
Having trained as a pilot, he became the youngest jet transport rated pilot in the world at the age of 19.
He is also a founder and member of the board of trustees of non-profit organisation OceanGate Foundation, which aims to catalyse emerging marine technology to further discoveries in marine science, history, and archaeology.
In an interview with Sky News back in February, Mr Rush spoke about visiting the Titanic wreck.
“What really strikes you is how beautiful it is,” he said. “You don’t normally see that on a shipwreck.
“It is an amazingly beautiful wreck.”
When asked if they can go inside the wreckage, Mr Rush said: “You can see inside, we dipped down and saw the grand staircase and saw some of the chandeliers still hanging.
“Next year we are hoping to send a small robot inside but for now we stay on the outside.”
Paul-Henry Nargeolet is a former commander who served in the French Navy for 25 years.
During his service he became the captain of the deep submergence group of the navy.
After leaving the navy he joined the French Institute for Research and Exploitation of the Sea (IFREMER), according to The Five Deeps Expedition – a company that assembles scientists, engineers and submersible operators for missions.
Mr Nargeolet has already led several expeditions to the Titanic site and has been involved in numerous scientific and technical expeditions around the world.
Elon Musk is being sued for failing to disclose his purchase of more than 5% of Twitter stock in a timely fashion.
The world’s richest man bought the stock in March 2022 and the complaint by the US Securities and Exchange Commission (SEC) said the delay allowed him to continue buying Twitter stock at artificially low prices.
In papers filed in Washington DC federal court, the SEC said the move allowed Mr Musk to underpay by at least $150m (£123m).
The commission wants Mr Musk to pay a civil fine and give up profits he was not entitled to.
In response to the lawsuit a lawyer for the multi-billionaire said: “Mr Musk has done nothing wrong and everyone sees this sham for what it is.”
An SEC rule requires investors to disclose within 10 calendar days when they cross a 5% ownership threshold.
The SEC said Mr Musk did not disclose his state until 4 April 2022, 11 days after the deadline – by which point he owned more than 9% of Twitter’s shares.

Twitter’s share price rose by more than 27% following Mr Musk’s disclosure, the SEC added.
Mr Musk later purchased Twitter for $44bn (£36bn) in October 2022 and renamed the social media site X.
Since the election of Donald Trump, Mr Musk has been put in charge of leading a newly created Department of Government Efficiency (DOGE) alongside former Republican presidential candidate Vivek Ramaswamy.
The president-elect said the department would work to reduce government bureaucracy, slash excess regulations, cut wasteful expenditures and restructure federal agencies.
US president-elect Donald Trump has suggested Israel and Hamas could agree a Gaza ceasefire by the end of the week.
Talks between Israeli and Hamas representatives resumed in the Qatari capital Doha yesterday, after US President Joe Biden indicated a deal to stop the fighting was “on the brink” on Monday.
A draft agreement has been sent to both sides. It includes provisions for the release of hostages and a phased Israeli troop withdrawal from Gaza.
Qatar says Israel and Hamas are at their “closest point” yet to a ceasefire deal.
Two Hamas officials said the group has accepted the draft agreement, with Israel still considering the deal.
An Israeli official said a deal is close but “we are not there” yet.
More than 46,500 Palestinians have been killed in Gaza since Israel launched its ground offensive in the aftermath of the 7 October attacks, according to the territory’s Hamas-run health ministry.
President Biden said it would include a hostage release deal and a “surge” of aid to Palestinians, in his final foreign policy speech as president.
“So many innocent people have been killed, so many communities have been destroyed. Palestinian people deserve peace,” he said.
“The deal would free the hostages, halt the fighting, provide security to Israel, and allow us to significantly surge humanitarian assistance to the Palestinians who suffered terribly in this war that Hamas started.”
Qatari mediators have sent Israel and Hamas a draft proposal for an agreement to halt the fighting.
President-elect Donald Trump has also discussed a possible peace deal during a phone interview with the Newsmax channel.
“We’re very close to getting it done and they have to get it done,” he said.
“If they don’t get it done, there’s going to be a lot of trouble out there, a lot of trouble, like they have never seen before.
“And they will get it done. And I understand there’s been a handshake and they’re getting it finished and maybe by the end of the week. But it has to take place, it has to take place.”
Israeli official: Former Hamas leader held up deal
Speaking on Tuesday as negotiations resumed in Qatar, an anonymous Israeli official said that an agreement was “close, but we are not there”.
They accused Hamas of previously “dictating, not negotiating” but said this has changed in the last few weeks.
“Yahya Sinwar was the main obstacle for a deal,” they added.
Sinwar, believed to be the mastermind of the 7 October attacks, led Hamas following the assassination of his predecessor but was himself killed in October last year.
Under Sinwar, the Israeli official claimed, Hamas was “not in a rush” to bring a hostage deal but this has changed since his death and since the IDF “started to dismantle the Shia axis”.

Biden: ‘Never, never, never, ever give up’
Iran ‘weaker than it’s been in decades’
Yesterday, President Biden also hailed Washington’s support for Israel during two Iranian attacks in 2024.
“All told, Iran is weaker than it’s been in decades,” the president said.
Mr Biden claimed America’s adversaries were weaker than when he took office four years ago and that the US was “winning the worldwide competition”.
“Compared to four years ago, America is stronger, our alliances are stronger, our adversaries and competitors are weaker,” he said.
“We have not gone to war to make these things happen.”
The US president is expected to give a farewell address on Wednesday.
The deal would see a number of things happen in a first stage, with negotiations for the second stage beginning in the third week of the ceasefire.
It would also allow a surge in humanitarian aid into Gaza, which has been devastated by more than a year of war.
Details of what the draft proposal entails have been emerging on Tuesday, reported by Israeli and Palestinian officials.
Hostages to be returned
In the first stage of the potential ceasefire, 33 hostages would be set free.
These include women (including female soldiers), children, men over the age of 50, wounded and sick.
Israelbelieves most of these hostages are alive but there has not been any official confirmation from Hamas.
In return for the release of the hostages, Israel would free more than 1,000 Palestinian prisoners and detainees.
People serving long sentences for deadly attacks would be included in this but Hamas fighters who took part in the 7 October attack would not be released.
An arrangement to prevent Palestinian “terrorists” from going back to the West Bank would be included in the deal, an anonymous Israeli official said.
The agreement also includes a phased withdrawal of Israeli forces from Gaza, with IDF troops remaining in the border perimeter to defend Israeli border towns and villages.
Security arrangements would be implemented at the Philadelphi corridor – a narrow strip of land that runs along the border between Egypt and Gaza – with Israel withdrawing from parts of it after the first few days of the deal.
The Rafah Crossing between Egypt and Gaza would start to work gradually to allow the crossing of people who are sick and other humanitarian cases out of Gaza for treatment.
Unarmed North Gaza residents would be allowed to return to their homes, with a mechanism introduced to ensure no weapons are moved there.
“We will not leave the Gaza Strip until all our hostages are back home,” the Israeli official said.
What will happen to Gaza in the future?
There is less detail about the future of Gaza – from how it will be governed, to any guarantees that this agreement will bring a permanent end to the war.
“The only thing that can answer for now is that we are ready for a ceasefire,” the Israeli official said.
“This is a long ceasefire and the deal that is being discussed right now is for a long one. There is a big price for releasing the hostages and we are ready to pay this price.”
The international community has said Gaza must be run by Palestinians, but there has not been a consensus about how this should be done – and the draft ceasefire agreement does not seem to address this either.
In the past, Israel has said it will not end the war leaving Hamas in power. It also previously rejected the possibility of the Palestinian Authority, which exercises limited governing powers in the West Bank, from taking over the administration of Gaza.
Since the beginning of its military campaign in Gaza, Israel has also said it would retain security control over the territory after the fighting ends.
