Alpen Blitz was a compact steel roller coaster that operated at Six Flags Great Adventure from 1976 to 1978.
So they purchased compact and inexpensive coasters called Jumbo Jet and Big Fury.
The Alpen Blitz was located in the area later occupied by the "Haunted Castle".
After the 1978 season when "Lightning Loops" opened, it was determined that Alpen Blitz was no longer needed.
Big Fury was also sold and replaced with the Wild Rider at the end of the 1977 season.
