Besides your roller coasters, carousels, and Ferris wheels, a staple attraction of any major amusement park is the drop tower ride. While common today, these freefall attractions don't have a long, hundred-year history like the roller coaster or amusement park. The first tower rides didn't appear until the 1980s and didn't start catching on until the 1990s when the technology and ride experience improved enough to make them "can't miss" attractions.
