 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.  

Asiana Airlines Flight 214 tried to abort its landing and come in for another try just 1 1/2 seconds before it crashed Saturday at San Francisco airport, killing two people and injuring dozens of others.

That was the information gleaned from the jetliner's cockpit voice recorder, the head of the National Transportation Safety Board said at a Sunday news conference. NTSB chief Deborah Hersman also said about 7 seconds prior to impact, there was a call to increase speed.

She said the flight data recorder captured the entire flight.

The National Transportation Safety Board released its final report Tuesday on a deadly 2009 train derailment in Winnebago County.
