A transnational inquiry has been launched to determine accountability for the deaths of five passengers aboard the OceanGate Expeditions submersible that imploded during a descent to the wreckage of the Titanic in the North Atlantic, the United States Coast Guard announced Sunday. Maritime agencies from Canada, France and Britain are joining an investigation that will be led by the Coast Guard, Capt. Jason Neubauer said during a news conference at Coast Guard Base Boston. Neubauer said the priority of the investigation, known as a Marine Board of Investigation, or MBI, "is to recover items from the seafloor." Neubauer said investigators will also determine "the cause of this marine casualty" and establish accountability.

Navy SEAL Jake Zweig responds to the intense search for the missing Titanic submarine on'Fox & Friends.' Efforts to recover the remains of the Titan submersible that suffered a catastrophic implosion near the Titanic wreckage are currently underway, and as of Sunday, had descended to the seafloor for a fourth dive. Last Thursday, the U.S. Coast Guard confirmed that a debris field located about 1,600 feet from the wreckage of the Titanic was in fact that of the missing Titan submersible. The underwater vessel was carrying five men on board when it lost contact with its surface ship about an hour and 45 minutes after descending to the Titanic. South Wellfleet, Massachusetts-based Pelagic Research Services (PRS) was contacted by OceanGate, the company behind Titan, for use of its remotely operated vehicles, or "ROVs," to assist with the search. Pelagic Research Services continues to assist the Transportation Safety Board of Canada, U.S. Coast Guard, and U.S. National Transportation Safety Board with Titan recovery efforts near the Titanic wreckage.

TORONTO/OTTAWA – Officials say a Porter Airlines flight approaching Toronto's island airport took evasive action to avoid a suspected drone, injuring two flight attendants. Julie Leroux of Canada's Transportation Safety Board said the near collision occurred at 7:30 a.m. Leroux says the object involved in the near-miss was likely an unmanned aerial vehicle. Porter spokesman Brad Cicero says two flight attendants sustained minor injuries. They were taken to a hospital and released.
