A more modern steel looping
roller coaster design by
Bolliger & Mabillard. The
track is below the riders and the
train however there is no
floor beneath the riders' feet. This causes the rider's feet to dangle above the track. This coaster type debuted in April of 1999 at
Six Flags Great Adventure in the form of
Medusa, a 142 foot groundbreaking roller coaster. My only experience with floorless roller coasters is
Batman Knight Flight. This coaster has an extra wide
lift hill over a good portion of the
park's lake. One of my best friends considers this one of his top three coasters, and I'm guessing for good reason. I personally enjoy the immense speed coupled with massive
inversion elements. As of October 2002, there seven floorless coasters, though many others are debated as possibly floorless.
Floorles coasters include:
Superman Krypton Coaster Six Flags Fiesta Texas - 168 feet, opened March 2000
Superman / la Atracción de Acero Warner Brothers Movie World - 164 feet, opened April 2002
Batman Knight Flight Six Flags Worlds of Adventure - 157 feet, opened May 2000
Medusa Six Flags Marine World - 150 feet, opened March 2000
Kraken SeaWorld Orlando - 149 feet, opened June 2000
Medusa Six Flags Great Adventure - 142 feet, opened April 1999
Batman - Dark Knight Six Flags New England - 118 feet, opened April 2002
