  • Karl Stanley rode inside OceanGate's Titan submersible in April 2019.
  • He raised concerns to OceanGate CEO Stockton Rush over the ship's hull shortly after that trip.
  • To his surprise, a report this week contained more information related to his dive inside the Titan.

An early passenger on OceanGate's Titan submersible didn't realize how close he was to experiencing the "catastrophic" failure that sealed the vessel's fate in 2023 until a year after the incident.
