Superman: Escape from Krypton is a steel shuttle roller coaster located at Six Flags Magic Mountain in Valencia, California. When it opened in 1997, it was the tallest roller coaster in the world, and its speed of 100 mph was tied for the fastest with Tower of Terror II, a similar roller coaster which opened two months earlier at Dreamworld in Australia. These two coasters were the first to utilize Linear Synchronous Motor technology to propel vehicles to top speed. To date, it is the only reverse freefall coaster left in existence after the dismantling of Tower of Terror II.
The intended opening date of 1996 was postponed because of several issues with the launch system. The ride was closed in late 2010 for refurbishment, and it emerged in 2011 as "Superman: Escape from Krypton".
