The Tornado is a wooden roller coaster located at Adventureland in Altoona, Iowa, near Des Moines.After leaving the station, the train coasts down a small incline, around a curve, and heads up the lift hill to the top of the first drop.This drop, which is the largest in the ride, can provide for some air time depending on where riders are seated on the train.On July 22, 2006, a loose board left on or near the track of the Tornado by a maintenance worker was responsible for injuring Mackenzie Jennings, an 11-year-old girl.She underwent surgery at Mercy Medical Center in Des Moines to remove a blood clot and reduce swelling in her head.
