What happens when your Six Flags roller coaster putters to a stop at the peak? Adventure-seeking riders found out on Friday when the Nitro at Great Adventure in Jackson, N.J. got stuck, and they were forced to walk down along the 230-foot tracks.

Six Flags representatives told New York's PIX-11 that the ride stopped on the hill due to a power failure. When working properly, the "hypercoaster" reaches speeds of 80 m.p.h and heights of 233 feet. You can literally see Philadelphia from the first hill, according to Six Flags' website.
