American Eagle is a wooden racing roller coaster located at Six Flags Great America. It was the first wooden roller coaster designed by Intamin of Switzerland and was built in 1981 by the contracting firm Figley-Wright.[1] While the records have since been broken, American Eagle had the longest drop and fastest speed among wooden roller coasters when it debuted and is still recognized as a top racing coaster in the United States. In 2006, American Eagle celebrated its Silver Anniversary.

Overview

Soaring high above the County Fair section of the park, this massive dual-track wooden racing coaster spans almost the entire southern edge of the park. The out-and-back design features a very recognizable 560-degree helix at the turnaround point and a first drop that dips 20 feet (6.1 m) below ground level. An original design feature was a set of holding brakes that would perch trains at the top of the lift hill for a brief moment, giving riders a bird's-eye view before releasing them to soar down the 147-foot (45 m)-tall (45 m) first drop at a 55-degree angle. Use of the holding brakes was short-lived and the brakes themselves were eventually removed so that the trains just go right down the drop. The ride was also originally designed to run with a total of six trains; however, that number has since been reduced to four (two per track). American Eagle uses three-bench, five-car trains built by the Philadelphia Toboggan Company. The trains were originally designed with single-position lap bars but are now equipped with individual lap bars and seatbelts, making the trains on both American Eagle and Viper similar.

Ride experience

Guests enter the queue area to the right of the KIDZOPOLIS section (originally Wiggles World). Prior to KIDZOPOLIS being built, guests entered the queue through the large "Eagle Tent," which had been used for a circus between 1976 and 1980. Approaching the station, the queue line splits, allowing guests to choose between riding the “Red Side” (left) and the “Blue Side” (right). Both sides offer similar ride experiences, although in 1991, 1996, 2002–2005, 2011 (from August 5 until September 17) and for the fall of 2013 the Blue Side ran its trains facing backward. Guests then enter the ride platform from their track's side of the station.

Upon boarding the train, riders fasten their seat belts and lower their individual lap bar into place. Both red and blue trains are dispatched simultaneously and make a 200-degree turn opposite each other and proceed toward the lift hill. The trains meet up again behind the station where they turn back 20 degrees and begin their ascent side by side. At the top of the lift hill, the trains slowly make their way toward the edge before careening down the first drop, reaching speeds of over 66 mph (106 km/h). Riders race over two small, yet powerful air-time-filled hills before traveling upward and leveling out into a set of trim brakes at the far end of the out-and-back layout. Here, trains are slowed and riders enter a massive 560-degree helix where they circle downward over a small marsh, gradually picking up speed along the way. The helix circles to the left, allowing the red train to pull away, being on the inside of the track. Riders fly out of the helix before the tracks finally separate. The blue train drops low to the earth in an attempt to gain back some of the ground it lost in the helix, while the red train rises up and passes over the blue. Both trains turn right 20 degrees until they are running parallel with each other but separated by the outbound tracks. The red train drops down after passing over the blue and flies over two more airtime hills while the blue train only leaps over one hill after turning its way through the wooden supports. Both trains then rise into the massive wooden structure of the lift hill and are slowed by a final set of trim brakes. Each train then dives opposite each other into a final 360-degree helix, often accompanied by much squealing from the wheels skidding on the metal rails as they negotiate the turn. The blue train circles at a significantly smaller radius in a final attempt at making up the ground it lost in the big helix. The two trains then emerge and rise into the brake run to determine the winner.

Race variables

Some races are close, but in most cases one side finishes far ahead of the other. Several variables factor into this occurrence. One is that the two sides are not linked with one another and ride operators on each side must try and time their dispatches together. Another big factor is weight and weight distribution. A train fully loaded with riders will gain more momentum and travel faster than a train carrying no passengers at all. Also, trains with weight positioned more towards the front cars will allow the train to disengage from the lift sooner as the center of gravity passes over the apex of the hill. A final major factor is the brake pressure of the many trim brakes throughout the ride. Often, brakes will be applied stronger to one side of the track than the other, leading many riders to believe their race is being fixed. Other factors such as differences in track friction and wind speed play a lesser role. All variables being equal, however, the ride is designed to end in a tie.

Construction

The KIDZOPOLIS tent prior to 2007 was the entrance into American Eagle

American Eagle was built with approximately 1,360,000 feet (410,000 m) of lumber, 129,720 bolts, and 30,600 pounds of nails. Supports are attached to approximately 2,000 concrete footings that average 1.5 feet (0.46 m) in diameter and are 4.5 feet (1.4 m) deep. American Eagle was painted with over 9,000 gallons of white paint and took over 20,000 man hours to build.[2] American Eagle was designed by Curtis Summers, James Figley, and Leonard Wright. Marriott originally contacted John C. Allen to design the coaster, but he did not want to attempt it.

The tent that housed the American Eagle queue area from 1981 to 2006 was used as a circus tent from 1976 to 1980. In 2007, it was converted into a children's area named KIDZOPOLIS (originally Wiggles World). The new entrance is located to the right of KIDZOPOLIS, utilizing part of the entry building for the adjacent Dare Devil Dive skycoaster. The old entrance was demolished in 2006. The original bald eagle that was on the roof of the old entrance is being used again on the current entrance.
