Six Flags AstroWorld, also known simply as AstroWorld, was a seasonally operated amusement park in Houston, Texas. Owned and operated by Six Flags, the park was situated between Kirby Drive and Fannin Street, directly south of I-610. The park opened on June 1, 1968, and was developed originally and constructed as part of the Astrodomain, the brainchild of local philanthropist and former Houston mayor Roy Hofheinz, who intended it to complement the Astrodome. The Hofheinz family sold AstroWorld to Six Flags in 1978.
A stand-up roller coaster is a roller coaster where passengers aboard a train stand throughout the course of the ride. The first manufacturer to employ the format was TOGO, a Japanese company that converted two traditional roller coasters in 1982 to stand-up configurations. Arrow Dynamics followed suit in the United States the following year with their own conversion. The first roller coaster designed from the ground up as a stand-up coaster was King Cobra, built by TOGO, which opened at Kings Island in 1984. Intamin and Bolliger & Mabillard (B&M) have also designed stand-up models beginning in the 1990s, with the latest opening in 2023 as Pipeline: The Surf Coaster in SeaWorld Orlando.
Arrow Dynamics was an American manufacturing and engineering company that specialized in designing and building amusement park rides, especially roller coasters. Based in Clearfield, Utah, the company was the successor to Arrow Development (1946–1981) and Arrow Huss (1981–1986), which were responsible for several influential advancements in the amusement and theme park industries. Among the most significant was tubular steel track, which provided a smoother ride than the railroad style rails commonly used prior to the 1960s on wooden roller coasters. The Matterhorn Bobsleds at Disneyland, built in 1959, was Arrow's first roller coaster project.
A shuttle roller coaster is any roller coaster that ultimately does not make a complete circuit, but rather reverses at some point throughout its course and traverses the same track backwards. These are sometimes referred to as boomerang roller coasters, due to the ubiquity of Vekoma's Boomerang coaster model.
A suspended roller coaster is a type of steel roller coaster in which the car hangs from the bottom of the rolling stock by a pivoting fulcrum or hinge assembly. This allows the car and riders to swing side to side as the train races along the track. Due to the swing designs, these roller coasters cannot invert riders.
Texas Cyclone was a wooden roller coaster at the defunct Six Flags AstroWorld in Houston, Texas. Designed by Don Rosser and William Cobb, it was manufactured by Frontier Construction Company and opened to the public on June 12, 1976. Well-known for its airtime, the roller coaster was 93 feet (28 m) tall, 3,180 feet (970 m) long, and had a ride time of two minutes and fifteen seconds. Texas Cyclone was modeled after the original Coney Island Cyclone, which AstroWorld had originally intended to purchase and move to their park before realizing the process would be too expensive.

The Bat was a suspended roller coaster located at Kings Island amusement park in Mason, Ohio. Designed by Arrow Development, it was billed as the "first of its kind" in the world when it opened to the public on April 26, 1981. The suspended coaster concept was a radical departure from traditional roller coaster design, where guests ride below the track instead of above. Previous attempts to build coasters that hang from the track were unsuccessful and date as far back as the early 20th century. Arrow solved issues by utilizing modern technology in the design, including its tubular steel track developed in 1959 for Disneyland's Matterhorn Bobsleds.
Viper was a steel roller coaster located at Six Flags AstroWorld in Houston, Texas. Manufactured by Anton Schwarzkopf, the Looping Star model opened in 1989.

D. H. Morgan Manufacturing, later simply known as Morgan, was a manufacturer of roller coaster trains, custom amusement rides, roller coasters, children's rides and other amusement devices. Founded in 1983, the company was originally headquartered in Scotts Valley, California. In 1991, the company moved to La Selva Beach, California, and into a new 55,000-square-foot indoor manufacturing facility. That facility was later increased to 75,000 square feet. The company produced a variety of rides from 1983 until 2001, but is probably best known for its steel hyper coasters.
