Humongous Moves: Ship Sink
USS Kittiwake operated as a Navy submarine rescue vessel for nearly 50 years before being decommissioned in 1994. Now she's being transformed into an artificial reef and underwater adventure for sports divers to explore. She must survive the trek from Norfolk, VA to the Cayman Islands and sink on target to land upright on the Caribbean Sea floor. Meet the teams in charge of this titanic task and follow their 1,600-mile journey through winter storms and huge swells.
