A piece of the hull of the RMS Titanic surfaces Monday for the first time since 1912, when the doomed ship sank in the icy waters of the North Atlantic after it hit an iceberg off the coast of St. John's, Newfoundland, Canada. The section of the doomed ship will be included in a Titanic exhibition. The Discovery Channel will cover the salvage expedition live on Sunday at 6 p.m. MDT.
