Ranked among the deadliest sinkings of an ocean liner, the RMS Titanic is one legendary boat. It lies in wreckage at the bottom of the Atlantic Ocean, about 12,500 feet (3810 meters) beneath the waves. While Titanic enthusiasts can easily view artifacts in museums and related exhibits (safely, on land), some fanatics are determined to make the voyage below the ocean to see what remains in real life.
But the trip is extremely dangerous and potentially fatal, as the world is unfortunately witnessing in real-time, following news of a submersible called Titan that went missing Sunday on a journey to the wreckage, sparking an international search-and-rescue effort.
