Great American Scream Machine
Great American Scream Machine (GASM) is a wooden roller coaster located at Six Flags Over Georgia in Austell, Georgia, United States. Manufactured by Philadelphia Toboggan Coasters, the ride opened in 1973 as the tallest, longest, and fastest roller coaster in the world. Often shortened to GASM, the 105-foot-tall (32 m) ride reaches a maximum speed of 57 mph (92 km/h). At the time of opening, early riders were given a "Red Badge of Courage" button for riding the coaster. On May 21, 2017, Great American Scream Machine received an ACE landmark designation from American Coaster Enthusiasts, recognized for becoming the first wooden coaster built by Six Flags and for being well maintained.
