Engineers have successfully retrieved the remaining debris and presumed human remains from the Titan submersible. The Titan submersible met a tragic end during a daring dive to the depths of the Titanic shipwreck in June.

The Titan submersible imploded under the crushing water pressure and claimed the lives of all five passengers on board. The ill-fated submersible conducted multiple dives to the Titanic wreck, located 3,800 metres deep (12,467 feet) in the North Atlantic Ocean.

The search for the lost submersible and its occupants began soon after the incident. The recovery effort spanned several months. The United States Coast Guard confirmed the successful operation and the safe transport of the recovered debris to a US port.

Medical experts will undertake the task of analysing the presumed human remains.

One high-profile casualty of the Titan submersible disaster was Stockton Rush, the CEO of OceanGate, the company that manufactured and operated the experimental submersible. Court documents from the United States reveal that Rush disregarded safety warnings concerning the Titan submersible, potentially indicating a failure to adhere to critical safety protocols during its operation.

The other four passengers who tragically lost their lives on the Titan submersible were Shahzada Dawood, a 48-year-old British-Pakistani businessman, and his 19-year-old son, Suleman Dawood, British businessman Hamish Harding, and Paul-Henry Nargeolet, a 77-year-old former French navy diver.

The Titan submersible was constructed with a hull made from carbon fibre, featuring titanium end plates and a small window at one end. The use of carbon fibre is cost-effective and persistent. However, this choice is not common for deep-sea dives with human passengers. Its experimental design and material choices raise questions about safety.

OceanGate has halted all of its deep-sea operations. An international investigation into the disaster is ongoing. The United States Coast Guard has announced plans to conduct a public hearing at a later date to scrutinise the circumstances surrounding the dive.
