Springfield, Ohio (AP) -- An Ohio cardiologist has died piloting the small plane his wife says helped relieve the stresses of medicine.
Authorities say 56-year-old Wilhelm Kalweit was killed Saturday evening when his aircraft crashed in a field near a grass landing strip in the western Ohio community of Mount Victory.
Kalweit lived in the Springfield area, 45 miles away, and was on his way home from a trip to Canada, where he'd had some work done on the plane.
His wife, Suzanne Fachon-Kalweit, says the doctor decided to stop in Mount Victory to eat at a restaurant he liked.
No one else was on board the plane.
Federal and Hardin County investigators are trying to determine what caused the accident.
