The Tragic Fate of OceanGate's Titan Submersible.

The Titan submersible, which went missing on Sunday, suffered a catastrophic implosion that likely killed its pilot and four passengers instantly amid the intense water pressure in the deep North Atlantic. Experts had cautioned that under intense pressure at extreme depths the Titan’s hull could implode, which would result in instant death for anyone aboard the vessel. The craft was subjected to more external pressure due to its larger internal volume, and any defect could result in a “near-instantaneous implosion” in less than 40 milliseconds.
