On the evening of May 3, 1999, the residents of Oklahoma City were hit with a devastating tornado. Over the course of 85 minutes, the tornado covered 38 miles – sucking people and cars into the air, flattening homes and ripping up roads. The storm destroyed thousands of homes, left behind more than one billion dollars in damage and killed 41 people. Caught in the tornado's path were a young mother and child in a mobile home, a family trapped in a culvert, a father and son sheltering in a closet and scientists tracking the storm's every move.
