The final investigation into the 2023 Titan submersible implosion is out, and it paints the disaster as fully preventable — a story of one man ignoring every warning.

• The sub imploded on the way to the Titanic in 2023, killing all five aboard; 2025 data shows the crew had a last, futile minute trying to save themselves.
• CEO Stockton Rush built the sub from carbon fiber to cut costs — a cheap material that quietly cracks and peels apart under deep-sea pressure and had never been trusted for this before.
• Rush dressed up the project with NASA, Boeing, and university logos, but those groups later said they had no real involvement in the hull.
• A safety expert, David Lochridge, flagged cracks and flawed construction, got fired, then was sued into bankruptcy and silenced with a non-disclosure deal.
• Rush dodged safety inspections by relabeling paying passengers as "crew," and skipped the higher safety margins normally used for deep dives.

Outlook: The findings cement Titan as a preventable tragedy, and are likely to fuel tighter rules for private deep-sea tourism.
