Canadian filmmaker and deepsea explorer James Cameron said Tuesday that the implosion of the Titan submersible that killed five people last month was an extreme outlier in decades of safe exploration. Remotely operated vehicles have retrieved parts of the Titan from the ocean floor, as well as what are believed to be human remains. The submersible broke apart as it neared the Titanic wreckage on June 18, killing all five people aboard, including OceanGate CEO Stockton Rush. “It’s an emotional shock.”Cameron was in Ottawa Tuesday for the opening of a new exhibition about his own submersible, the Deepsea Challenger. Cameron also said he wouldn’t be surprised to see new regulatory efforts in response to the Titan implosion.
