The pilot of a small plane was killed when the aircraft went down in a field near Grand Lake in northeastern Oklahoma.
The Oklahoma Highway Patrol says the aircraft was found lying upside down in a field just west of U.S. 59 and Oklahoma 127 near Zena, Oklahoma.
Grand River Dam Authority police were told about 6 p.m. Wednesday that a plane that had taken off from Zena had failed to arrive as scheduled at Grove, Oklahoma. Authority Police Chief Brian Edwards says witnesses reported seeing the aircraft appear to have trouble gaining altitude.
The pilot has been identified as Bob Hudson. He and his wife were medical missionaries, routinely flying to Mexico.
