The company whose submersible vanished in the North Atlantic on a tourist dive to the wreck of the Titanic was repeatedly warned that there might be catastrophic safety problems posed by the way it was developed, documents show.
With five people aboard a vessel that if still functioning would have a dwindling amount of oxygen, an expanding international fleet of ships and airplanes is searching for the Titan, operated by OceanGate Expeditions. The undersea exploration company based in Everett, Washington, has been making yearly voyages to the Titanic since 2021.
