The U.S Coast Guard says the Titanic-bound submersible that went missing with five people on board suffered a “catastrophic implosion” ultimately killing everyone. Search crews located “five different major pieces of debris" identified from the Titan submersible. James Cameron was the director of the iconic “Titanic” film and has traveled down to the wreckage more than 30 times. He tells Anderson Cooper what he thinks happened to the vessel. Plus, retired Navy physician and current Florida International University professor Dr. Aileen Marty joins AC360 to discuss if the bodies of the five passengers will ever be recovered.To learn more about how CNN protects listener privacy, visit cnn.com/privacy
