SAUK RAPIDS, Minn. (AP) - St. Cloud's mayor says the two people killed when a small plane crashed into a house in Sauk Rapids were a German foreign exchange student hosted by his family and a commercial pilot who was a friend. Mayor Dave Kleis says 16-year-old Alexander Voigt and 60-year-old pilot, Scott Olson, were sightseeing when the single-engine plane hit a house Friday night. Kleis says Olson was giving Voigt an aerial tour of the St. Cloud area so the teen could take photos. The mayor says his family hosted Voigt as part of an exchange program. He was scheduled to return to Germany this week. Kleis has been in contact with his parents. Kleis says Olson was his friend. Voigt attended Technical High School.
