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.

NTSB joins investigation into sub incident
The U.S. National Transportation Safety Board will be participating in the multiagency investigation into the Titan sub incident, an NTSB spokesperson told ABC News.
The U.S. agency joins the U.S. Coast Guard and the Transportation Safety Board of Canada (TSB), which deployed its members to St. John’s, Newfoundland and Labrador.
The TSB says it will conduct a "safety investigation regarding the circumstances of this operation conducted by the Canadian-flagged vessel Polar Prince."

White House reacts to lost sub, thanks search crews
White House press secretary Karine Jean-Pierre said the administration's "hearts go out to the families and the loved ones of those who lost their lives" on the Titan submersible.
"They have been through a tragic ordeal over the past few days and we are keeping them in our thoughts and prayers," she said.
She also thanked all parties who participated in search and rescue efforts this week.
"We would also like to thank the United States Coast Guard, our Canadian, British and French partners, and everyone who participated in the search and rescue efforts these past couple of days," Jean-Pierre said. "This whole effort has been a testament to the skill and also the professionalism that the men and women who serve our nation continue to demonstrate, continue to show each and every day."

Who will be footing the bill for search and rescue? The US taxpayer
When the U.S. Coast Guard decided to launch a search and rescue operation for the missing OceanGate submersible near the Titanic wreckage site, they did so without OceanGate footing the bill, according to officials.
As a matter of Homeland Security policy and the law, the Coast Guard never asks a private company or individual to reimburse the government for the costs associated with search and rescue missions, according to the Coast Guard.
"The Coast Guard, as a matter of both law and policy, does not seek to recover the costs associated with Search and Rescue from the recipients of those services,” according to a U.S. Coast Guard spokesperson. "As a matter of law, 46 USC 2110(a)(5) prohibits the Coast Guard from collecting fees for the conduct of SAR operations: The Secretary may not collect a fee or charge under this subsection for any search or rescue service."

OceanGate co-founder defends development of submersible
OceanGate co-founder Guillermo Söhnlein is coming to the defense of late CEO Stockton Rush, one of those killed in the implosion of Titan, after criticism from director James Cameron, and others, who said the sub's carbon-fiber hull was dangerous.
"In this kind of community, there are completely different opinions and views about how to do things, how to design submersibles, how to engineer them, build them, how to operate in the dives," Söhnlein told the U.K.'s Times Radio on Friday. "But one thing that’s true of me and the other experts, is none of us were involved in the design, engineering, building, testing or even diving of the subs. So it’s impossible for anyone to really speculate from the outside."
Söhnlein co-founded OceanGate in 2009 with Rush and led several dives in the early days of the company. He left OceanGate in 2013, when Rush took over as CEO, but maintained a friendship and spoke to Rush just weeks before the doomed expedition, he said on Facebook.
Cameron, who not only directed the Oscar-winning film "Titanic" but is a prolific ocean explorer, criticized the use of a carbon-fiber hull in the construction of Titan, saying it was only a matter of time before it cracked under the pressure from repeated dives. Rush, in the past, defended its use, saying it had a better strength-to-buoyancy ratio than titanium.
"I was involved in the early phases of the overall development program during our predecessor subs to Titan, and I know from firsthand experience that we were extremely committed to safety and risk mitigation was a key part of the company culture," Söhnlein told Times Radio Friday.
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.
