The U.S. Coast Guard says a missing submersible imploded near the wreckage of the Titanic, killing all five people on board. Coast Guard officials said during a news conference Thursday that they've notified the families of the crew of the Titan, which has been missing for several days. Debris found during the search for the vessel “is consistent with a catastrophic implosion of the vessel,” said Rear Adm. John Mauger of the First Coast Guard District. “The outpouring of support in this highly complex search operation has been great appreciated. Our most heartfelt condolences go out to the friends and loved ones of the crew,” Mauger said.
