Investigation launched into Titan sub implosion and pilot's legacy.

The Coast Guard has launched an investigation into the implosion of the Titan sub, which was attempting a dive to the wreckage of the Titanic with five people on board. The investigation will include authorities from Canada, France, and the United Kingdom. Investigators will look into possible misconduct, incompetence, negligence, unskillfulness, or willful violation of law by OceanGate, the company that operated the Titan, or by the Coast Guard itself. The U.S. Navy will not be using the Flyaway Deep Ocean Salvage System to assist in retrieving debris. The Transportation Safety Board of Canada has also begun an investigation into the incident.
