Of the three Vekoma Flying Dutchmans, only Batwing still operates at its original location: Stealth was relocated to Carowinds and renamed "BORG Assimilator" from 2004 to 2007, and now operates as Nighthawk, while X-Flight operated at Kings Island as Firehawk until October 28, 2018. Vekoma has also designed a new, more compact flying roller coaster model nicknamed the 'Stingray'. Its first installation is at theSuzhou Giant Wheel Park in Suzhou, China, which opened on August 18, 2009. The ride was removed in 2018. Vekoma's flying roller coasters have a 54-inch height restriction. Swiss manufacturer Bolliger & Mabillard (B&M) unveiled its Flying Coaster model in 2002 with "Air" at Alton Towers (renamed Galactica in 2016), followed later in the year by "" at Six Flags Over Georgia. In this version, the rider takes a sitting position with their legs dangling in a similar fashion to B&M's inverted roller coaster. Mechanisms in the station lift the car up to the track, placing passengers in a flying position for the duration of the ride. Flying roller coasters from B&M use a combination chest/waist harness that is hinged above the riders' heads. Once seated, the rider pulls down the harness, which (like the Vekoma model) locks into slots in the sides of the armrests. This single mechanism locks the rider's waist in place with a large padded cushion and provides a rubberized padded vest to secure the chest. The vest includes seat-belt-style tensioners above the shoulders to support a wider range of body types. At the ankles, two flaps hold the legs in position, and close as the harness is locked in place. Tatsu at Six Flags Magic Mountain was the world's longest flying coaster until The Flying Dinosaur at Universal Studios Japan surpassed it in March 2016. Bolliger & Mabillard currently holds the record for the longest, tallest and fastest flying roller coaster in the world, "Flying Dinosaur", at Universal Studios Japan. Italy's Zamperla produces a flying roller coaster model dubbed 'Volare' (Italian for ""to fly""). Riders lie down in the cars, which hang from an upper rail at a 45 degree angle. The car is then lifted up into a flying position while holding the riders inside. This model is very compact and affordable (estimated to be US$6 million) and comes with a unique spiral lift hill in which a tall spinning column with 2 vertical poles connected to it which push the cars up the spiral track.
