Underwater Drone Entered Titanic's Sister Ship Britannic — What It Captured Is Haunting

In 1916, Titanic's bigger, safer sister ship Britannic sank in just 55 minutes off the Greek island of Kea, and for decades nobody could agree on why. This video follows every expedition that went down to find out, from Jacques Cousteau's 1976 dives and the US Navy's nuclear research submarine NR 1 to the robot cameras and rebreather divers who finally reached her open portholes, open watertight doors and crushed bow. You'll learn what really sank the hospital ship, what happened to the 30 people who died, why two divers lost their lives exploring her, and what the 2025 expedition brought back from 400 feet down.
