Investigation underway into cause of Titan submersible implosion.

The US Coast Guard is leading an investigation into the loss of the Titan submersible that was carrying five people to the Titanic to determine what caused it to implode. The salvage operations are ongoing, and they have mapped the accident site. The convening of a Marine Board of Investigation is the highest level of investigation conducted by the US Coast Guard. The Flyaway Deep Ocean Salvage System had the capability of lifting an intact Titan back to the surface, but the Navy won't be using it. The Transportation Safety Board of Canada has also begun an investigation into the loss of the submersible.
