A roller coaster element that simulates the same turn planes may make. Named for Max Immelmann, a World War I German Ace and the aerial maneuver it simulates. The coaster begins a half vertical loop up. At the top of the half-loop the coaster then does a 180-inversion, or barrel roll, to be back right side up. Began as a Bolliger & Mabillard (B&M) inverted coaster element only but then with the advent of Wildfire at Silver Dollar City, the element appeared on standard steel roller coasters.
