Great American Scream Machine was once the world's tallest and fastest looping roller coaster, and actually helped Six Flags Great Adventure climb out of years of decline. The ride was quite rough but its impact was significant for Great Adventure. In this video, I cover Great Adventure's uprise in the 1970s, it's decline in the 1980s, how Scream Machine helped turn the park around, and all of Scream Machine's operational issues.
