FIRST FATAL CRASH
When the Southwest Airlines 737 failed to stop in time on the runway at Chicago's Midway Airport and crashed through a fence and onto a street, killing a 6-year-old passenger in a car, it was the first fatal accident in the airline's 35-year history. As tragic as this was, it is an amazing safety record. One current theory is that the plane's reverse thrusters did not engage in time.
