A roller coaster inversion is a roller coaster element in which the track turns riders upside-down and then returns them to an upright position. Early forms of inversions were circular in nature and date back to 1848 on the Centrifugal railway in Paris. These vertical loops produced massive g-force that was often dangerous to riders. As a result, the element eventually became non-existent with the last rides to feature the looping inversions being dismantled during the Great Depression. In 1975, designers from Arrow Development created the corkscrew, reviving interest in the inversion during the modern age of steel roller coasters. Elements have since evolved from simple corkscrews and vertical loops to more complex inversions such as Immelmann loops and cobra rolls. The Smiler at Alton Towers holds the world record for the number of inversions on a roller coaster with 14.

Boomerang: Coast to Coaster is a steel roller coaster of shuttle design currently in use at four different Six Flags & EPR theme parks. The ride was designed and manufactured by Vekoma, and is considered as one of its boomerang models. Each coaster has one train with a capacity of 28, two across in each row. Unlike Vekoma's suspended trains, "Boomerang: Coast to Coaster" operates a sit-down design. When the coaster starts, the train is pulled backwards up the lift hill, then dropped through the loading gate through a cobra roll and then one loop. At the end of this cycle the train is pulled up the lift hill at the end of the track, then dropped once again allowing the train to go back through the loops backwards, hence the name "Boomerang: Coast to Coaster."
Flashback is a steel roller coaster of shuttle design currently operating at Six Flags New England. The ride has one train with a capacity of twenty-eight riders, two across in each row.

At the end of this cycle, the train is pulled up the lift hill at the end of the track. It is then released, allowing the train to traverse the track in the opposite direction. The ride is an off-the-shelf Vekoma Boomerang design common in many amusement parks.
