Engineer Don Kramer is slated to testify as the investigation continues into the implosion of OceanGate's Titan submersible. The Coast Guard opened a public hearing earlier this month that is part of a high level investigation into the cause of the implosion. Coast Guard officials noted at the start of the hearing that the submersible had not been independently reviewed, as is standard practice. Wreckage of the Titan was subsequently found on the ocean floor about 330 yards (300 meters) off the bow of the Titanic, Coast Guard officials said. OceanGate said it has been fully cooperating with the Coast Guard and NTSB investigations since they began.
