Superman: Ultimate Flight is the name of three flying roller coasters currently operating at three Six Flags amusement parks in the United States, those being Six Flags Over Georgia, Six Flags Great Adventure and Six Flags Great America. Each of these steel coasters were designed and built by Swiss manufacturer Bolliger & Mabillard and opened in 2002 and 2003. Since 2003, Six Flags has installed Superman: Ultimate Flight in three of their parks. Themed to the popular comic book character, Superman: Ultimate Flight simulates flying by positioning its passengers parallel to the track, supported by harnesses and facing the ground through most of the ride. In the station, riders board the train sitting down. After the train is locked and checked, the trains are raised into the flying position. After the ride, the seats are lowered back into the sitting position for the next round of riders.
