Ninety-nine years ago tonight, RMS Titanic struck an iceberg in the North Atlantic and, early the next morning, sunk. It’s been abetting adventures—and, on occasion, French-Canadian power ballads—ever since.The wreck itself was discovered in 1985 by Robert Ballard, who was clandestinely being funded by the U.S. Navy to search for two nuclear submarines that sunk in the 1960s. A battle broke out over admiralty law—that is, who owns the liner.A company called RMS Titanic, Inc. was formed to “own” and exhibit the salvage, and it wasn’t till last year that a U.S. District Judge finally granted the outfit full custody under the “Maritime Law of Finds.”It was also last year that this expedition returned to the wreck—now more or less disintegrated. Before it disappeared forever, robots were used to record a 3D replica of the site for posterity. The computer model should be available by next year’s hundredth anniversary.
