Boomerang is a coaster type made by Vekoma, named after the original boomerang. The first Boomerang began operation in 1984 at Rafaela Padilla in Puebla, México (which has since been moved to Six Flags México), and it has become one of the most repeated roller coaster designs in the world, with 41 Boomerangs operating as of 2011, another two "Standing but not operating" or in storage, and one currently under construction.
