The Euro-Fighter is a type of steel roller coaster developed by German manufacturer Gerstlauer. First launched in 2003, a trademark feature of the roller coaster is its beyond-vertical drop, which reaches an angle greater than 90 degrees. The majority of examples across the world feature a vertical chain-driven lift hill and have a single roller coaster car with two rows of four seats. A number of different track elements are possible, including vertical loops, diving loops and barrel rolls. Most Euro-Fighter installations feature a custom-designed track but every design so far has included the trademark beyond-vertical drop.
