Five passengers aboard missing submarine identified

The five passengers who traveled aboard a submarine to view the wreckage of the Titanic but did not return last Sunday have now been identified. Pakistani tycoon Shahzada Dawood and his son Suleman; Action Aviation Chairman Hamish Harding; French adventurer Paul-Henry Nargeolet; and Ocean Gate CEO Stockton Rush are said to be members of the unaccounted-for submarine.

The family of Shahzada Dawood and his son Suleman Dawood confirmed that both are among the passengers on the submarine. "On Sunday, June 18, Mr. Shahzada Dawood, Vice Chairman of Engro Corporation Limited, along with his son, Suleman, embarked on a journey to visit the remnants of the Titanic in the Atlantic Ocean. All that we know so far is that contact was lost with their submersible craft. There is limited information available beyond this that we know, and we humbly request that speculation and theorization is avoided," the relatives said in a statement picked up by CNN.

It was known that Harding and Nargeolet were also traveling aboard the vessel after the British man posted on his Facebook account confirming his attendance on the trip along with the French adventurer.
