The ill-fated Titan submersible is back in the spotlight this week as the U.S. Coast Guard holds an investigatory hearing into the circumstances surrounding the implosion of OceanGate s deep-sea vessel last year, a tragedy that killed all five people on board.

The first two days of testimony have painted an alarming picture of the way OceanGate founder Stockton Rush, who died while piloting the vessel, allegedly ran his company, handled safety concerns from his employees, kept outsiders away from the project, and rushed to bring his submersible to the Titanic wreckage.

Here are the biggest new pieces of information that have been revealed at the hearing thus far, including new images of the vessels wreckage and details about the crews last communications.
