Titanic Sub: Family Sacrifices and Tragedies.

Christine Dawood revealed in her first interview since the tragedy that she had intended to take part in the doomed Titanic expedition but stepped aside so her son could go instead. Her son, Suleman, was a Rubik's Cube obsessive who took the puzzle with him on the Titan submersible. The submersible went missing on June 18, and debris from the sub was found by search teams, indicating that the vessel had suffered a catastrophic implosion, killing all five people on board. The Dawood family is from a prominent Pakistani business family, and they will work to continue Shahzada's work and legacy.
