A man stole a light plane and threatened to crash it into the landmark Sky Tower in New Zealand's largest city, Auckland, before plunging the craft into the sea Saturday night, police said. "It arose from a domestic situation. A man with a pilot's license stole a light plane and threatened to crash into the Sky Tower," Auckland police spokeswoman Phillipa White told The Associated Press. "He's crashed into the harbor ... and emergency services are out there now." At 328 meters (1,076 feet), Sky Tower claims to be the tallest tower in the Southern Hemisphere. There was no immediate word on the man's condition. He was believed to be alone in the plane. TV1 said the plane flew close to the Sky Tower after dark, and reported that its pilot had been in contact with police. New Zealand held national elections Saturday, and both Prime Minister Helen Clark and opposition National Party leader Don Brash were due to hold election rallies in Auckland later Saturday night. TV1 reported that police had arrived outside Clark's house, but it was not immediately clear if they were scheduled to be there because it was election night or to beef up security due to the plane incident.
