Canada is investigating why the Titanic-bound submersible imploded

The Transportation Safety Board of Canada said Saturday that it’s conducting an investigation into the loss of the Titan submersible and has been speaking with those who traveled on Titan’s mothership, the Polar Prince.
The development comes as authorities from the U.S. and Canada began the process of probing the cause of the underwater implosion and grappled with questions of who was responsible for determining how the tragedy unfolded.
Maritime agencies are searching the area in the North Atlantic where the vessel was destroyed, killing all five people aboard. Debris was located about 12,500 feet (3,810 meters) underwater, several hundred feet away from the Titanic wreckage it was on its way to explore.
“We are conducting a safety investigation in Canada given that this was a Canadian-flagged vessel that departed a Canadian port and was involved in this occurrence, albeit in international waters,” said Kathy Fox, chair of the transportation board. “Other agencies may choose to conduct investigations and that’s up to them.”
