An anonymous reader quotes a report from PBS: The historic ocean liner SS United States will be intentionally sunk Wednesday off the coast of the Florida panhandle. Live coverage of the sinking of the SS United States is expected to start at 1 p.m. EST, with the sinking expected at 2 p.m. EST. Watch live in the video player above. In its heyday, the SS United States crushed the trans-Atlantic speed record, which it still holds. The luxury ocean liner took only three days to cross from New York to Europe on its maiden voyage in 1952. Carrying presidents and Hollywood stars, the nearly 1,000-foot vessel was a technical marvel of its time. However, the rise of air travel and high operating costs sunk its economic viability, and the ship was pulled from service in 1969. The ocean liner sat at Philadelphia's Pier 82 for nearly 30 years. After a contentious back and forth with a pier landlord over rent and docking fees, Okaloosa County in Florida eventually stepped in to purchase the ship and bring it to the Gulf of Mexico to become the world's largest artificial reef. The multi-million dollar project is also aimed at creating an economic development opportunity as a major diving attraction. "It was our goal to make sure that she wasn't lost forever," said David Lawrence, a member of the board for the SS United States Conservancy, the group that sold the vessel to the Florida county. Like the ship's unconventional life, it will also have an unconventional sinking. Federal environmental and explosives rules prevent the county from using explosives. Instead, tanks inside the ship have been removed and large holes were cut into the decks. Once the valves are opened, water will flood the hull, sinking the ship. Resting at 180 feet below the surface of the water, the SS United States will join more than 500 artificial reefs in Okaloosa County, which the county relies on to support the underwater ecosystem.
