A man and woman fell overboard from a cruise ship in the Gulf of Mexico early Sunday, but both were rescued after a four-hour search and appeared to be in good condition, a cruise line spokeswoman said. The 22-year-old man and 20-year-old woman fell 50 to 60 feet (15 to 18 meters) from a cabin balcony, said Julie Benson, spokeswoman for Princess Cruises. She said the cruise line did not know how they fell overboard, although it appears to have been an accident. Their ship, Princess Cruise's Grand Princess, was about 150 miles (240 kilometers) off the coast of Galveston, Texas, at the time. The captain turned the ship around after friends of the man and woman notified the crew at about 1:30 a.m. CDT that they had gone overboard, Benson said. The ship's crew used high-powered spotlights and rescue boats in the search. One passenger was rescued by the ship's boats at 5:30 a.m. and the other at 6 a.m., according to a statement by the cruise line.
