UNDATED -- The National Transportation Safety Board has issued a preliminary report into the plane crash that killed two people and destroyed a Sauk Rapids home.

The report does not list a cause of the crash that killed the pilot, 60-year-old Scott Olson and passenger 16-year-old Alexander Voigt. Voigt was a foreign exchange student from Germany who had been in St. Cloud for about 10 months.

The report states Olson was flying an experimental airplane and was operating without a flight plan which is normal for that type of flight.

The NTSB report shows Olson took off from St. Cloud Regional Airport at 8:10 p.m. and crashed into the home 24 minutes later.

A final report on the crash isn't expected for several weeks.
