Banging sounds were heard during Titan search Tuesday, according to an internal government memo
From CNN’s Priscilla Alvarez
Crews searching for the Titan submersible heard banging sounds every 30 minutes Tuesday, according to an internal government memo update on the search.
Four hours later, after additional sonar devices were deployed, banging was still heard, the memo said. It was unclear when the banging was heard Tuesday or for how long, based on the memo.
A subsequent update sent Tuesday night suggested more sounds were heard, though it was not described as “banging.”
“Additional acoustic feedback was heard and will assist in vectoring surface assets and also indicating continued hope of survivors,” according to that update.
A Canadian P3 aircraft also located a white rectangular object in the water, according to that update, but another ship set to investigate was diverted to help research the acoustic feedback instead, according to that update.
The Joint Rescue Coordination Center is working to find an underwater remote-operated vehicle to help assist in the search, according to the memo.
CNN has reached out to OceanGate, the US Coast Guard in Boston, and Canadian authorities for comment.
Rolling Stone was the first to report the news Tuesday night.

OceanGate explains why the Titan submersible is not "classed"
From CNN’s Celina Tebor
In a 2019 blog post on OceanGate’s website, the company said most marine operations “require that chartered vessels are ‘classed’ by an independent group such as the American Bureau of Shipping (ABS), DNV/GL, Lloyd’s Register, or one of the many others.”
This "classing" system ensures vessels are designed and built following regulations such as the number of life rafts or types of materials used.
But the Titan submersible that went missing en route to the Titanic wreck, is not classed, the blog post said.
It said classing innovative designs often requires a multiyear approval process, which gets in the way of rapid innovation.
Classing agencies “do not ensure that operators adhere to proper operating procedures and decision-making processes – two areas that are much more important for mitigating risks at sea. The vast majority of marine (and aviation) accidents are a result of operator error, not mechanical failure,” it said.
“Classing assures ship owners, insurers, and regulators that vessels are designed, constructed, and inspected to accepted standards. Classing may be effective at filtering out unsatisfactory designers and builders, but the established standards do little to weed out subpar vessel operators – because classing agencies only focus on validating the physical vessel,” it read.
OceanGate touted Titan's safety features, despite conflicting info over its development
From CNN’s Celina Tebor
In a 2021 court filing, OceanGate’s legal representative touted the specifications and a hull monitoring system that he called “an unparalleled safety feature” built into the Titan submersible.
The legal representative informed the US District Court for the Eastern District of Virginia, which oversees matters related to the Titanic, of the company’s expedition plans at the time.
The filing lays out the Titan’s testing details and its specifications, including that it had undergone more than 50 test dives and detailing its 5-inch-thick carbon fiber and titanium hull.
The filing said OceanGate’s vessel was the result of more than eight years of work, including “detailed engineering and development work under a company-issued $5 million contract to the University of Washington’s Applied Physics Laboratory.”
But according to the University of Washington, the laboratory never dealt with the design or engineering for OceanGate’s Titan vessel.
In a statement to CNN, Kevin Williams, the executive director of UW’s Applied Physics Laboratory, said the lab’s expertise involved “only shallow water implementation,” and “the Laboratory was not involved in the design, engineering or testing of the TITAN submersible used in the RMS TITANIC expedition.”
In 2022, the legal representative updated the Virginia court on OceanGate’s expeditions in another court filing. Two former employees of OceanGate Expeditions separately brought up similar safety concerns about the thickness of the now-missing Titan submersible’s hull when they were employed by the company years ago.
A statement from a research lab appears to show conflicting information about the engineering and testing that went into the development of the vessel.
David Lochridge worked as an independent contractor for OceanGate in 2015, then as an employee between 2016 and 2018, according to court filings. He served as the company’s director of marine operations.
The company terminated his employment and sued Lochridge and his wife in 2018, claiming he shared confidential information, misappropriated trade secrets, and used the company for immigration assistance then manufactured a reason to be fired. The lawsuit noted that Lochridge is not an engineer, calling him a submersible pilot and a diver.
In a counter-filing, Lochridge claimed he was wrongfully terminated for raising concerns about the safety and testing of the Titan.
Lochridge’s countersuit says he was tasked by OceanGate’s CEO, Stockton Rush, to perform an inspection of the submersible. It says Lochridge brought up concerns that no non-destructive testing had been performed on the Titan’s hull to check for “delaminations, porosity, and voids of sufficient adhesion of the glue being used due to the thickness of the hull.”
The suit says that when Lochridge raised the issue, he was told that no equipment existed to perform such a test.
The lawsuit was settled and dismissed in November 2018. The terms of the settlement were not disclosed, and Lochridge could not be reached for comment.
Court filings from the company indicate there was much additional testing after Lochridge’s time at OceanGate, and it’s unclear whether any of his concerns were addressed as the vessel was developed.
Another former employee of OceanGate who worked briefly for the company during the same period as Lochridge spoke to CNN on the condition of anonymity because he is not authorized to speak publicly.
He said he became concerned when the carbon fiber hull of the Titan arrived, echoing Lochridge’s concerns about its thickness and adhesion in his conversation with CNN. He said the hull had only been built to be 5 inches thick, while he said company engineers told him they had expected it to be 7 inches thick.
The former employee worked at the submersible company for two and a half months in 2017; he was an operations technician who assisted with towing submersibles out into the ocean and preparing them for the diving operation.
He said more concerns were raised by contractors and employees during his time at OceanGate and Rush became defensive and shied away from answering questions during all-staff meetings. When the former employee raised concerns that OceanGate could potentially be violating a US law relating to Coast Guard inspections directly to Rush, the CEO outright dismissed them, the former employee said, and that’s when he resigned.
CNN has reached out to OceanGate for comment. The US Coast Guard released an image showing the search pattern for the Titan submersible — and provided an update on existing and incoming resources that are expected to aid in the search for the underwater vessel.
A New York Air National Guard C-130 arrived at about 4 p.m. to assist in the search, joining "Deep Energy," a Bahamian research vessel that arrived around 7 a.m., and was conducting remotely operated vehicle (ROV) operations, the Coast Guard said.
The following additional assets are also en route to the scene, the US Coast Guard said:
· Canadian CGS John Cabot
· Canadian CGS Ann Harvey
· Canadian CGS Terry Fox
· Canadian CGS Atlantic Merlin (ROV)
· Motor Vessel Horizon Arctic
· Commercial Vessel Skandi Vinland (ROV)
· French Research Vessel L’Atalante (ROV)
· His Majesty's Canadian Ship Glace Bay (mobile decompression chamber and medical personnel)
“This is a complex search effort which requires multiple agencies with subject matter expertise and specialized equipment which we have gained through the unified command,” Captain Jamie Frederick, the response coordinator from the First Coast Guard District, said in a press release.
“While the Coast Guard has assumed the role of Search and Rescue Mission Coordinator, we do not have all of the necessary expertise and equipment required in a search of this nature,” he added. “The Unified Command brings that expertise and additional capability together to maximize effort in solving this complex problem.”
