With a maximum speed of 68 mph (109.4 km/h), it is the fourth fastest roller coaster in the UK, behind The Big One at Blackpool Pleasure Beach, and Stealth and Hyperia at Thorpe Park.
In Theme Park Review's YouTube video of the IAAPA 2011 trade show, Walter Bolliger stated that development of the Dive Coaster model began between 1994 and 1995.
The attraction's construction site was surrounded by a patrol guard who kept it hidden, and the park initially did not reveal much information about it to the general public.
Details about SW4 were not revealed until March 1998, including its name Oblivion and its status as the "worlds first vertical drop roller coaster".
[2] Oblivion's opening was accompanied by a large promotional campaign, including appearances on Blue Peter, news channels and Corn Flakes cereal box packets.
Through the buildings, an unnamed man stood in darkness (played by actor Renny Krupinski) briefs riders from overhead television screens.
In the heavily stylised videos, the sinister figure explains at length the supposed physical and psychological effects of riding on Oblivion.
The third queueline video features an alter-ego character (who appears glowing white) arguing with his counterpart as to whether Oblivion is truly safe for riders.
[15] Five years later, SheiKra opened at Busch Gardens Tampa Bay as the first Dive Coaster with a 90 degree vertical drop and a splashdown element.
[16][17] In 2015, a ride named Oblivion: The Black Hole opened at Gardaland, becoming the first vertical drop roller coaster in Italy.
