X-Flight

X-Flight is a steel roller coaster located at Six Flags Great America in Gurnee, Illinois. Designed and built by Bolliger & Mabillard, the ride opened as the fourth Wing Coaster in the world and the second in the United States on May 16, 2012. It replaced both the Splashwater Falls and Great American Raceway attractions. The 3,000-foot-long roller coaster features barrel rolls, high-speed drops, and a signature fly-through element, where the train narrowly misses a support structure – designed to look like an air traffic control tower – as it passes through an opening known as a keyhole element.
