Dive 12,467 feet to the ocean’s depths and learn the answers to some previously unsolved mysteries about the Titanic when the Community Library presents a special live screening of Atlantic Production’s “Back to the Titanic.”

The new acclaimed National Geographic documentary will air at 2 p.m. Thursday, June 18. Emmy Award-winning filmmaker Anthony Geffen, who spends holidays in Sun Valley away from his home in England, will field questions from the audience about the film afterwards.

The documentary follows the Caladan Oceanic’s expedition—the first manned expedition to RMS Titanic in nearly 15 years. It captures the wreck for the first time in 4K.

The lens focuses on the staterooms of Benjamin Guggenheim, one of the richest passengers on board. And it shows how the iconic Captain’s bathtub is gone, as the whole deck house on that side of the ship is collapsing as the Titanic returns to nature.

The team used submersible camera systems to capture highly accurate photo-real 3D models of the RMS Titanic, revealing that the ship is slowly being destroyed by metal-eating bacteria, salt corrosion and ocean currents.

The Titanic has lain on the bottom of thee ocean 370 miles off the coast of Newfoundland, Canada, for more than a century. The passenger liner—the largest ship of its time—hit an iceberg on its maiden voyage from Southampton, England, to New York in 1912. More than 1,500 of the 2,200 passengers and crew onboard died.
