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 and says Olson was his friend.

The Star Tribune says a National Transportation Safety Board investigator arrived at the damaged house owned by Jeff Hille on Saturday afternoon. Hille, a teacher at Sauk Rapids-Rice High School, said Friday night that his brother-in-law, Kole Heckendorf, was in an upstairs bedroom when he heard an explosion, saw flames and smoke, and jumped out a second-story window. Heckendorf was not injured.

The NTSB is continuing to investigate the crash.
