Boomerang, Steel roller coaster in Six Flags St. Louis, United States.
Boomerang is a steel roller coaster at Six Flags St. Louis that sends riders forward and backward through a sequence of loops and inversions. The train holds 28 passengers across seven cars and delivers twists and turns that challenge riders in unexpected directions.
The coaster originally ran as Flashback at Six Flags Over Texas from 1989 to 2012, then moved to Six Flags St. Louis in 2013. This relocation brought the ride to a new home where it continues to operate with the same thrilling design.
The addition of Boomerang established Six Flags St. Louis as the location with the highest number of roller coasters in Missouri.
Guests should be aware of height requirements, as this ride is physically intense and not suited for all visitors. Wearing loose clothing and bracing for outdoor conditions on the track helps make the experience more comfortable.
The ride launches backward up a lift hill, sending riders in reverse before they experience the twists and loops. This backward start creates a surprising moment that sets this coaster apart from traditional designs.
