Tragic Deaths of Titanic Expert, Adventurer, CEO, and Father-Son Duo in Titan's Implosion

A renowned Titanic expert, a world record-holding adventurer, two members of one of Pakistan's wealthiest families, and the CEO of the company leading an expedition to the Titanic were killed aboard the Titan submersible when it imploded in the Atlantic Ocean. The search for the submersible and any clues to explain what happened underwater was ongoing Thursday after a deep-sea robot found debris near the Titanic shipwreck.
