Four people were injured when a small plane crashed at the Chicago Rockford International Airport Monday evening.
Deputy Chief Brian Kunce with the airport fire department said the King Air C-90 twin-engine plane was about 200 yards from a runway when it stuck a ditch, bounced over a fence and came to rest on the airport grounds. Kunce says the plane didn't catch fire.
The extent of the injuries was not immediately known. Two people -- one of whom was unconscious -- had to be extricated from the plane.
It was very windy at the time of the crash, but Kunce says it's too early to tell what caused it. The National Transportation Safety Board is investigating.
