Custom Jumbo Jet?

Just north of Chicago in Gurnee IL is a little park called Six Flags Great America and the have an Anton Schwarzkopf roller coaster that is one of the last “Speedracer” roller coaster ever built. You might call it a custom Jumbo Jet. The “Speedracer” named the Whizzer is a permanent model where as the Jumbo Jet and other “Jet Star” models are not. Both have a spiral lift hill and thats where the similarities end. Take a ride on the Whizzer to find out for yourself.
