Jetline is a roller coaster at Gröna Lund in Stockholm, Sweden. It has gained worldwide recognition for its curved lift hill, an anomaly amongst roller coasters. It was opened in 1988 and was a clone of the Knightmare roller coaster at Camelot Theme Park however It was modified in 1997 by Mauer Söhne to have a longer and steeper drop. Knightmare also pulled 5Gs while Jetline only pulls 4.5. A tunnel was also added at the bottom of the first drop. From Wikipedia
