Rare video of 1986 dive in Titanic wreck released

Rare and in some cases never before publicly seen video of the 1986 dive through the wreckage of the Titanic is being released by the Woods Hole Oceanographic Institution.The more than 80 minutes of footage on the institution's YouTube channel on Wednesday chronicles some of the remarkable achievements of the dive led by Robert Ballard.

The expedition marked the first time human eyes had seen the giant ocean liner since it struck an iceberg and sank in the frigid North Atlantic. The vessel met its fate on its maiden voyage from Southampton, England, to New York City in April 1912.About 1,500 people died. The vessel now lies in some 2.4 miles below the surface of the ocean. The footage was released to mark the 25th anniversary debut of the Academy Award-winning movie, “Titanic.”
