(NewsNation) — The Coast Guard’s investigative hearing into the 2023 Titan submersible implosion continues Tuesday after a long day of testimony Monday.
A key employee who labeled the experimental submersible unsafe prior to its last, fatal voyage was set to testify Tuesday before Coast Guard investigators.
David Lochridge is one of the most anticipated witnesses to appear before a commission trying to determine what caused the Titan to implode en route to the wreckage of the Titanic last year, killing all five on board. Lochridge is former operations director for OceanGate, the company that owned the Titan and brought it on several dives to the Titanic going back to 2021.
On Monday, witnesses painted a picture of a troubled company that was impatient to get its unconventionally designed craft into the water. The accident set off a worldwide debate about the future of private undersea exploration.

Investigators also revealed Monday what they believe was the fate of the five passengers on board, showing an animated timeline of events leading up to and following the Titan’s deep-sea implosion in June 2023.
The Coast Guard’s Marine Board of Investigation, which is responsible for probing the cause of marine disasters, will continue to question witnesses and review key evidence from the incident during a hearing Tuesday.
The goal of the hearing is to determine what led to the deadly implosion during the dive and to examine possible regulatory failures regarding the submersible’s design, operation and safety protocols.

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 OceanGate co-founder Stockton 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.
