Rare footage of first sight of Titanic wreck released – video

Rare and in some cases never before publicly seen video of a 1986 dive through the wreckage of the Titanic is being released by the Woods Hole Oceanographic Institution. More than 80 minutes of footage on the institution's YouTube channel on Wednesday chronicle some of the remarkable achievements of the dive led by Robert Ballard. The expedition marked the first time human eyes had seen the ocean liner since it struck an iceberg and sank in the frigid North Atlantic in 1912. The footage was released to mark the 25th anniversary of the Oscar-winning film Titanic
