An expedition to the Titanic wreckage site in the North Atlantic went awry on Sunday when the submersible carrying five people, including at least three paying passengers, went missing. The Coast Guard is leading the search efforts in an area more than two miles below the ocean's surface, but the submersible has not yet been located. The two professional crew members on board were OceanGate's CEO and founder, Stockton Rush, and a French veteran of deep-sea exploration.
