Which type of roller coaster utilizes pneumatic technology for launches?

The correct answer, which identifies the type of roller coaster that utilizes pneumatic technology for launches, is the air-launch coaster. This type of coaster employs compressed air to propel the train out of the station at high speeds, rather than using a traditional lift hill. The pneumatic system allows for quick acceleration and can provide a thrilling launch experience, often resulting in more intense ride experiences with rapid changes in speed and direction.

Air-launch coasters are designed to give riders the sensation of being 'launched' rather than simply 'climbed', making them distinct from gravity-powered coasters that rely on the force of gravity for movement. The pneumatic launch system can produce smoother acceleration and is often used in modern coaster designs to enhance the thrill factor.

Gravity-powered coasters rely solely on the gravitational pull to navigate tracks, which does not involve any form of mechanical launch technology. Vertical drop coasters are often characterized by their steep drops but primarily depend on gravity to achieve their speeds. Hybrid coasters blend traditional steel and wooden construction but do not typically utilize pneumatic technology for launches. Thus, air-launch coasters are unique in employing this innovative method, making the selection of this option the most fitting response.
