Missing Titanic submersible live updates: Texts show OceanGate CEO dismissed concerns
Five people, including the company CEO, were aboard the sub when it imploded.
All passengers are believed to be lost after a desperate dayslong search for a submersible carrying five people that vanished while on a tour of the Titanic wreckage off the coast of Newfoundland, Canada.
The 21-foot deep-sea vessel, operated by OceanGate Expeditions, lost contact about an hour and 45 minutes after submerging on Sunday morning with a 96-hour oxygen supply. That amount of breathable air was forecast to run out on Thursday morning, according to the United States Coast Guard, which was coordinating the multinational search and rescue efforts.

Company behind Titan overstated details of partnerships with Boeing, others
The company behind the submersible that imploded exaggerated the details of the industry partnerships behind the development and engineering of the underwater vessel.
In some public statements, OceanGate suggested the Titan -- its only vessel able to reach Titanic depths -- was designed and engineered with the assistance of entities such as Boeing, the University of Washington and the National Aeronautics and Space Administration. In statements to ABC News, each entity described its role, or lack thereof, as more limited than sometimes stated by OceanGate.
When asked about these exaggerations about the role of partnerships in the development of the Titan submersible, an OceanGate representative declined to comment on the matter.

Probe seeks answers on why Titanic sub imploded
U.S. Coast Guard officials conceded they are facing a daunting investigation to determine what caused the Titan submersible to implode underwater near the wreckage of the Titanic, killing all five explorers aboard.
Officials said the 21-foot-long Titan was found in pieces by a remotely operated vehicle on a smooth section of ocean floor more than 2 miles beneath the surface.
"This was an incredibly complex case and we're still working to develop details for the timeline involved with this casualty and the response," Mauger said.

What a 'catastrophic implosion' means
The Titan submersible suffered a "catastrophic implosion," the U.S. Coast Guard determined.
At the depth of the Titanic, which sits 3,800 meters below sea level, the pressure reaches a level 380 times the atmospheric pressure on the Earth's surface, Stefan Williams, a professor of marine robotics at the University of Sydney, said in a blog post on Tuesday.
A fault or failure in the hull of the Titan could have led to an implosion, as the vessel gave way to the high pressure of the deep sea, Williams said.
The implosion of a submersible delivers immense force, oceanographer Bob Ballard told ABC News on Thursday.

Navy likely detected sound of the implosion on Sunday: Official
A senior U.S. Navy official confirmed to ABC News that an underwater acoustic detection system heard on Sunday what was likely the implosion of the Titan submersible. The information was immediately shared with the U.S. Coast Guard on Sunday and analysis continued afterwards.
"The U.S. Navy conducted an analysis of acoustic data and detected an anomaly consistent with an implosion or explosion in the general vicinity of where the Titan submersible was operating when communications were lost," the senior official told ABC News in a statement. "While not definitive, this information was immediately shared with the Incident Commander to assist with the ongoing search and rescue mission."
According to the official, "This information was considered with the compilation of additional acoustic data provided by other partners and the decision was made to continue our mission as a search and rescue and make every effort to save the lives on board.”
Separately, a U.S. defense official said an analysis of the “banging” noises picked up by sonar buoys were not from the missing submersible but were either natural ocean sounds, biological noises or noises associated with the surface response vessels.

Samad Dawood says loss of brother and nephew is 'heartbreaking,' family is 'devastated'
Samad Dawood, the brother of Shahzada Dawood, one of the passengers who died in the submersible, said losing his brother and nephew, Suleman Dawood, is heartbreaking.
"This is beyond what you could ever imagine in terms of the kind of hardships and struggle that we've had. I think what we've seen is enormous tragedy and devastation and a lot of emotions. Obviously we were hoping to hear some good news about the rescue and them coming back. It was heartbreaking to find out that that's not the case," Samad Dawood told ABC News.
Samad Dawood said his brother had a strong sense of adventure and curiosity about the world.
"He was always the kind of person who has this incredible love for the world," Samad Dawood said.
"He inspired us curiosity. And he was a guy who just wanted to go out there, experience what the world had to offer, even though he he himself pushed himself to do it. So they made adventures to go to Antarctica, to go to Greenland and to go to Africa and go to the rapids," Samad Dawood said.
This sense of adventure was passed on to Shahzada Dawood's son, 19-year-old Suleman Dawood, who was also in the submersible. Suleman Dawood had traveled to all seven continents, according to Samad Dawood.
"He was so filled with humbleness and gratitude," Samad Dawood said.
"We're deeply grateful for all the support and the love and the effort that the people have made, working tireless nights being optimistic in giving a sense of hope, giving that transparency to us. But obviously we were devastated as a family ... that we couldn't get them back safe," Samad Dawood said.
