Six Flags Great America. Notice how the bars on the restraint system are not what actually hold the rider in place. The design of a Wing Coaster differs from many traditional steel roller coasters in that its trains are not located above or below the track but rather on the sides, a configuration that give riders the impression of free flight. Also, because there is nothing on top of the track and only steel beams holding each ends of the train together, all current Wing Coasters have an object (that relates to the theme) that covers the steel beams and adds to the experience. The restraints on the trains are also different. Instead of simply having the traditional over-the-shoulder restraint bar used on many
inverted roller coasters, the Wing Coaster restraints are similar to Bolliger & Mabillard's
Flying Coaster, which includes a vest restraint and a waist-level restraint with bars on the side for the rider to hold on to. The Wing Coaster's differences extended to the station layout of the station, which requires the queue to split in two halves, allowing riders to board the train where the seats sit level with the track. ==Installations==
