Stealth (roller coaster) 4.88

Stealth is a steel roller coaster located in the Amity area of Thorpe Park in Surrey, England, UK. Built and designed by Intamin of Switzerland for £12 million, the Accelerator Coaster model opened in 2006. Riders reach a maximum height of and accelerate from 0-80 mph in 1.9 seconds. It has the fastest acceleration of any coaster in the UK, and is the tallest among launch coasters in the country. At the base of the top hat element on either side, riders may experience up to 4.5 G.Ride experienceThe launch sequence begins with the retracting of the brake fins as the train attaches to the catch car. An American-accented voice announces, "Place your heads back, face forwards, hold on tight and brace yourself." The message is repeated as five red lights turn on one by one, before shouting "Three, two, one. Go, go, go!" The lights turn green and the train accelerates to 80mph in 1.9 seconds into a steep, vertical top hat element. The train then turns 90 degrees to the left and descends the top hat element into another 90 degree turn. A second bunny hop hill follows producing a brief moment of weightlessness before the train enters the brake run and returns to the station.Roll backsAs with many Intamin Launch Coasters, Stealth experiences occasional roll backs. Roll backs occur when a train is unable to complete the course, specifically failing to make it over the top hat, as a result of energy loss.
