One person was killed and two others were injured when an airplane skimmed over a farm field and crashed on a gravel road.
The Cessna 172 Skyhawk crashed about 1 p.m. Sunday, shortly after taking off from the Decorah Municipal Airport.
Killed in the accident was Michele K. Olson, 41, of Wahkon, Minn., the Winneshiek County sheriff's office said.
The pilot, David Olson, 43, also of Wahkon, was injured. He was hospitalized in La Crosse, Wis., where he was listed in critical condition on Monday.
The Olsons were married.
The other passenger, Amanda R. Remer, 18, of Isle, Minn., was hospitalized in Rochester, Minn., where she also was in critical condition.
Winneshiek County Sheriff Leon Bohr told Cedar Rapids television station KCRG-TV that the plane hit the ground hard and ended up nose down in the ditch.
Witnesses reported the plane was flying low before it crashed.
Denise Baumler said she was washing windows when she heard a loud noise. The plane was flying about 30 feet above a soybean field, flew around her barn and then crashed.
Several telephone calls from witnesses led authorities to the crash site.
The Federal Aviation Administration and the National Transportation Safety Board are investigating.
