Flashback is a steel roller coaster of shuttle design currently in use at Six Flags New England. The ride has one train with a capacity of twenty-eight riders, two across in each row. 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 released, allowing the train to go back through the loops backwards, hence the name of the coaster. The ride is an off-the-shelf Vekoma Boomerang design common in many amusement parks.
The ride started out at Nanhu Amusement Park in China, but was sold soon after opening, Before it moved to Six Flags New England, the roller coaster was located at Kentucky Kingdom where it was known as The Vampire, with its controversial slogan "Give blood at your local park". The ride opened at Kingdom Kingdom in 1990, when the park reopened after being closed for two seasons. The ride continued to operate at the park until 1999, when it experienced multiple breakdowns. It was later closed in 1999 and was moved to Six Flags New England, where it was renamed Flashback and opened to the public in May 2000. It continues to operate as of 2014.
