The search for the missing submarine with five passengers is still on, as experts estimate they have less than 30 hours of oxygen left.
A millionaire father and son team, a wealthy adventurer, and a diver with decades of experience studying the Titanic are among the five individuals on board the submersible that has gone missing while on its way to see the world's most famous wreckage.
Authorities said the small craft, approximately the size of a minivan, was carrying five people when it lost communication with its mothership on Sunday morning, about one hour and 45 minutes into its descent to survey the Titanic disaster.
While the names of individuals on board have not been disclosed, British businessman Hamish Harding, Pakistani billionaire Shahzada Dawood and his son Sulaiman Dawood, and French diver Paul-Henri Nargeolet have been confirmed.

Harding, who has completed several challenging missions, is based in the United Arab Emirates and is a skilled jet pilot. He is the CEO of Action Aviation, a plane brokerage. Harding was on board the submersible, according to a corporate statement posted on social media.
The Dawoods are a well-known business family in Pakistan. Their company, Dawood Hercules Corporation, is one of the largest in the country, with a portfolio that includes energy, petrochemicals, fertilizers, information technology, and food and agriculture.
According to the Dawood Hercules Corporation's website, the corporation is led by family patriarch Hussain Dawood, with his sons Shahzada and Abdul Samad overseeing various divisions and his daughter Sabrina Dawood in charge of the charitable arm.
Shahzada Dawood is also a trustee of the SETI Institute in California and several other foundations. On Saturday, Harding announced on social media that diver Paul-Henri Nargeolet was set to join him on the dive.
