CONCORDIA, Kan. (AP) — Authorities say four people escaped injury in the crash of a small plane in north-central Kansas.

The single-propeller aircraft overturned shortly Monday afternoon in a field off a runway at the airport in Concordia.

Kansas Highway Patrol Trooper Ben Gardner says two children, ages 5 and 7, were on board along with their father and grandfather. The grandfather was piloting the plane and coming in for a landing after a pleasure flight.

Gardner says the two adults were walking around and talking to troopers at the scene, but were taken to a hospital to be checked as a precaution.
