2023 Titan submersible incident

On 18 June 2023, Titan, a submersible operated by OceanGate, disappeared in international waters in the North Atlantic Ocean, approximately 400 nautical miles (740 km) off the coast of Newfoundland, Canada. The submersible, carrying five people, which includes Stockton Rush (CEO of OceanGate), Shahzada Dawood, Suleman Dawood, Hamish Harding, and Paul-Henri Nargeole was part of a tourist expedition to observe the wreck of the Titanic. Communication with Titan was lost 1 hour and 45 minutes into its dive to the wreck site. Authorities were alerted when it failed to resurface at the scheduled time later that day.
