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

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. #Britannic #Titanic #Shipwreck #HMHSBritannic #OceanExploration #History Britannic, HMHS Britannic, Titanic sister ship, Britannic wreck, Britannic sinking, Britannic shipwreck, underwater drone shipwreck, Jacques Cousteau Britannic, Robert Ballard Britannic, NR-1 submarine, Violet Jessop, Kea Greece shipwreck, hospital ship 1916, WW1 shipwreck, Olympic class liners, shipwreck documentary, deep sea exploration, wreck diving, Britannic 2025 expedition, ocean mysteries, Titanic documentary
