The vertical loop

Great American Scream Machine was a steel sit-down roller coaster located at Six Flags Great Adventure in Jackson, New Jersey, USA. Built by Arrow Dynamics, it opened in 1989 as the tallest and fastest looping roller coaster in the world. It was built along with two other sister coasters known as Shockwave (dismantled in 2002) at Six Flags Great America and Viper at Six Flags Magic Mountain. Although another rolller coaster with the same name exists at Six Flags Over Georgia, that ride is an out and back wooden roller coaster.

Vertical Loop
Vertical Loop
Double Corkscrew

After the Lift Hill and drop, there is 3 vertical loops, a brake run, the Batwing, a Double Corkscrew before a turn around into the station.



The double-corkscrew element

3 trains with 7 cars per train. Riders are arranged 2 across in 2 rows for a total of 28 riders per train

The trains were named Freedom (red), Liberty (white), and Spirit (blue)- each representing the colors of the American flag. The over-the-shoulder restrain handles.


  • After the first season, the top of the vertical loops were replaced by track with additional stregnth bracing. This was due to problems on other Arrow Dynamics coasters, such as Shockwave at Six Flags Great America. The original top of the first loop can be seen in the monkey enclosure at the Wild Safari. Along with this, a trim brake was installed after the first loop. This was not designed to stop the train, it is only used to adjust the speed at temperatures of over 90 degrees.
  • In 2009, the white train (Liberty) was ad-wrapped as an advert for one of the rides sponsors, got2b Glued Styling Spiking Glue, a hair gel. This was the first ride in the park to have this, but adverts were later placed on Kingda Ka and El Toro trains for Karati Kid and Stride Gum respectively.


All the colors of the ride and the surrounding area resemble the American flag. The track was painted red with white supports. The trains were named Freedom (red), Liberty (white), and Spirit (blue). The ground under the ride hasd a red and white pattern resembling the stripes on the American flag and the station building was white with blue trim.
