Carnival Cruise Lines Pirate Attack

U.S. Navy personnel cleared unexploded grenades from a luxury cruise ship Monday, two days after pirates attacked the vessel off the coast of Africa. The 150 passengers had been on board when pirates in two boats armed with machine guns and rocket-propelled grenades attacked the Spirit on Saturday. The 440-foot ship eventually was able to outrun the pirates off the coast of Somalia. The crew of the Spirit used a Long Range Acoustic Device to blast the pirate ships with ultra high sound waves while the ship's captain changed course and shifted into high speed heading for the open ocean.
