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.

'Underwater noises' detected but search 'yielded negative results,' US Coast Guard says
The U.S. Coast Guard announced via Twitter early Wednesday that a Canadian aircraft with sonar capabilities had "detected underwater noises in the search area."
Remotely operated vehicle operations (ROV) were then relocated "in an attempt to explore the origin of the noises," according to the Coast Guard.
"Those ROV searches have yielded negative results but continue," the Coast Guard tweeted.
Lawsuit alleged flaws with Titanic sub now missing
A former employee of OceanGate alleged in a 2018 counterclaim lawsuit that he was fired for raising concerns about quality control and testing of potential flaws in the same experimental submersible that went missing this week.
David Lochridge, an engineer and submarine pilot, claimed in his counterclaim against OceanGate that he was hired in 2015 by the Everett, Washington, company to ensure the safety of all crew and clients during the submersible and surface operations of the vessel called Titan. But when he expressed concerns about the design and testing of the minisub's hull, he said he was terminated by the company.
OceanGate had initially sued Lochridge alleging, among other things, breach of contract, fraud and misappropriation of trade secrets -- all claims he denied.
In its lawsuit, OceanGate accused Lochridge of breaching his contract by discussing the company's confidential information with the Occupational Health and Safety Administration "when he filed a false report claiming that he was discharged in retaliation for being a whistleblower."

Experts expressed Titan safety concerns in 2018 letter
Members of a committee specializing in submersibles expressed "unanimous concern regarding the development" of Titan in a 2018 letter addressed to OceanGate CEO Stockton Rush, who is one of the passengers aboard the missing vessel.
The letter was obtained by The New York Times and was later authenticated by ABC News.
The letter warned of possible "catastrophic" problems with Titan's development that could have "serious consequences for everyone in the industry." The letter goes on to say that OceanGate's safety claims were "misleading to the public" and insisted Titan be reviewed by a third-party organization.
The letter, which was addressed from the Marine Technology Society, was never approved to be sent to OceanGate though was quickly leaked to its CEO, according to committee chair William Kohnen.
"The letter did represent in 2018 the consensus by many people in the industry that they were not considering following the standard safety protocols and designs that the industry uses," Kohnen told ABC News.
Though he wishes it was not leaked at the time, nor now to The New York Times, Kohnen said he stands by the letter and its warnings.
"The company had indicated that their state of innovation was beyond, beyond what was allowable within the regulatory standards we have today and that they would proceed without certification," Kohnen said. "That worried a number of people in the industry."
Kohnen acknowledged that OceanGate did "heed" some of the comments made in the 2018 letter.

Former ABC News correspondent recounts moment his sub was trapped in Titanic's propeller
In 2000, Dr. Michael Guillen, then an ABC News correspondent, was filming from the wreck of the Titanic when his vessel became trapped in the propeller.
"When we collided with the propeller, and I started seeing those big chunks of metal raining down on us … the first reaction I had was, 'This can't be happening,'" he recalled to ABC News on Tuesday.
"We got caught by this underwater turn and just drove us right into the blades," Guillen said.
"This voice came into my head and said, you know, 'This is how it's going to end for you,'" he recalled. "I'll never forget those words."
"I'm very aware of what these poor souls on board the ship the Titan are experiencing," he said. "I am just heartbroken about it."
