Firebird is a floorless roller coaster located at Six Flags America in Prince George's County, Maryland.[1] The roller coaster had originally debuted in 1990 as a stand-up roller coaster named Iron Wolf at Six Flags Great America. It was later relocated to Six Flags America in 2012 and renamed Apocalypse, under which it operated until 2018.[2]
The roller coaster was the first to be built by Swiss manufacturer Bolliger & Mabillard.[3] When known as Iron Wolf, the roller coaster briefly held world records among stand-up roller coasters for height (100-foot or 30-metre) and speed (55 miles per hour or 89 kilometres per hour) before being surpassed several years later.
