For the roller coaster at Six Flags America, see Batwing (Six Flags America).
The element was first used on Orient Express, where it was called a Kamikaze Kurve. Orient Express was demolished after the 2003 season.
On Arrow Dynamics roller coasters, such as Great American Scream Machine at Six Flags Great Adventure, it is known as a boomerang, however on Bolliger & Mabillard roller coasters, such as Montu at Busch Gardens Tampa and Afterburn at Carowinds, it is known as a batwing.
