Manufactured by Intamin and designed by Werner Stengel, Kingda Ka opened as the tallest and fastest roller coaster in the world on May 21, 2005, surpassing Top Thrill Dragster. It is the second strata coaster ever built, exceeding 400 feet (120 m) in height, and the last to remain in operation after Top Thrill Dragster closed in 2021.

The launched roller coaster is a modern form of roller coaster. A launched coaster initiates a ride with high amounts of acceleration via one or a series of linear induction motors (LIM), linear synchronous motors (LSM), catapults, tires, chains, or other mechanisms employing hydraulic or pneumatic power, along a launch track. This mode of acceleration powers many of the fastest rollercoasters in the world.
A drop tower or big drop is a type of amusement ride incorporating a central structure or tower. Drop towers vary in height, passenger capacity, lift type, and brake type. Many are custom-made, although there are some mass-produced designs. The most widely sold drop towers have been manufactured by Intamin and S&S Sansei, however Larson International and Funtime have their own drop tower models available as well. Riders initially experience a sense of weightlessness via free fall, followed by rapid deceleration, after which a magnetic brake system brings the ride to a stop. The entire experience generally lasts less than one minute.

In the context of amusement rides, air time, or airtime, refers to the time during which riders of a roller coaster or other ride experience either frictionless or negative G-forces. The negative g-forces that a rider experiences is what creates the sensation the rider feels of floating out of their seat. With roller coasters, air time is usually achieved when the train travels over a hill at speed. There are different sensations a rider will feel depending on the ride being an ejector or floater airtime ride.
