Mother reveals son's desire to go on Titanic wreck voyage led to his tragic death on submersible.

The mother of Suleman Dawood, a 19-year-old passenger aboard the Titan submersible that imploded and killed all five people on board, said in an interview that her son was excited to go on the deep-sea expedition. She had intended to join her husband on the submersible before their plans were scuttled by the COVID-19 pandemic. The U.S. Coast Guard has launched an investigation into the submersible disaster to determine the cause of the implosion.
