Aside from the roller coaster built by Stakotra in 2005, where is the only other strata coaster in existence located?
Top Thrill Dragster:  When built in 2003, it was the first full circuit roller coaster to exceed 400 ft in height, and was the tallest roller coaster in the world, before being surpassed by Kingda Ka at Six Flags Great Adventure in May 2005.
