(NewsNation) — The Coast Guard’s investigative hearing into the 2023 Titan submersible implosion ended Thursday following testimony from two witnesses and is set to resume on Friday.
Renata Rojas is the latest person to testify who is connected to Titan owner OceanGate after an investigatory panel has listened to two days of testimony that raised questions about the company’s operations before the doomed mission. OceanGate co-founder and CEO Stockton Rush was among five people who died when the submersible imploded en route to the site of the Titanic wreck in June 2023.
OceanGate Scientific Director Steven Ross also testified before the hearing wrapped for the day. More witnesses are expected to testify with the hearing set to continue into next week.
Rojas refuted some testimony from previous witness David Lochridge regarding the OceanGate mission to the wreck of the Andrea Doria. She said that while the submersible did crash into the side of the wreck, there was no panicking or crying from passengers as Lochridge described.
During questioning about her role in various dives, Rojas, who paid to be a mission specialist on dives, described the role she and other passengers played. She also likened the project to NASA’s Apollo program of the 1960s, saying it was “testing by doing.”
Rojas said she was unaware that the submersible was not flagged by any country, which would have subjected it to safety regulations. She also noted the vessel did not have a classification because there are no regulatory bodies or organizations that provide classifications for carbon fiber submersibles.
The Titan’s carbon fiber hull has been cited as a likely cause for the implosion because the composite material can degrade over time and is more fragile than other materials typically used in building subsea vessels.
In an emotional closing statement, Rojas said the loss of her friends was still very raw but “exploration takes risks” and she hopes the implosion does not dampen innovation or other projects involving citizen scientists.
Earlier this month, the Coast Guard opened a public hearing that is part of a high-level investigation into the cause of the implosion. The public hearing began Tuesday, and some of the testimony has focused on the troubled nature of the company.
What has been learned so far?
Lochridge, one of the most anticipated witnesses to appear before the commission, is a key employee who labeled the experimental submersible unsafe before its last, fatal voyage.
He is the former operations director for OceanGate brought the Titan on several dives to the Titanic going back to 2021.
Per his testimony, Rush — who piloted the Titan — previously crashed another sub off the coast of Massachusetts in 2016.
Rush refused to hand over the control panel before eventually doing so after shipwrecking the vessel, according to Lochridge.
On Monday, witnesses painted a picture of a troubled company that was impatient to get its unconventionally designed craft into the water. The accident sparked a worldwide debate about the future of private undersea exploration.

The Titan, owned by OceanGate, made its last dive June 18, 2023. The craft lost contact with its support vessel an hour and 45 minutes into the dive. Five people were on board, diving 12,000 feet below the surface of the Atlantic Ocean.
The loss of communication launched a four-day search for the vessel, which ended when evidence of an implosion was found on the ocean floor. Officials concluded that the craft had been destroyed and all five people on board were killed.
Few vessels dive that deep into the ocean, and engineers and experts in the field noted previous problems with the Titan as well as warnings that the submersible was unsafe.
The search-and-recovery mission is estimated to have cost up to $1.6 million.
The Coast Guard quickly convened a high-level investigation into what happened. Concerns leading up to the investigation included the Titan’s unconventional design and its creator’s decision to forgo standard independent checks.
The investigation into the Titan implosion originally had a 12-month timeline but has been extended multiple times.
In addition to Rush, the implosion killed two members of a prominent Pakistani family, Shahzada Dawood and his son Suleman Dawood; British adventurer Hamish Harding; and Titanic expert Paul-Henri Nargeolet.
