A 46-year-old Texan is missing after falling 100 feet overboard from a Royal Caribbean cruise ship sailing off the Florida coast, reports ABC News. Another passenger reported seeing the man, identified as David Mossman, fall from the Navigator of the Seas around 11pm Saturday; the Coast Guard took over the search for him early Saturday, according to a Royal Caribbean statement, "and the ship resumed its journey to Port Everglades, Florida." It's not known what caused Mossman to fall. (More Royal Caribbean stories.)
