[1] The concept was conceived in 2010 and made into a scale model by Lithuanian artist Julijonas Urbonas, a PhD candidate at the Royal College of Art in London.

Urbonas, who had formerly been an amusement park employee, stated that the goal of his concept roller coaster is to take lives "with elegance and euphoria",[2] either for euthanasia or execution purposes.

[3] John Allen, who had been the president of the Philadelphia Toboggan Company, inspired Urbonas with his description of the "ultimate" roller coaster as one that "sends out 24 people and they all come back dead".

[4] The concept design of the layout begins with a steep-angled lift that takes riders up 500 metres (1,600 ft) to the top[1] (for comparison, the tallest roller coaster in the world, Kingda Ka, has a top hat that is 139 metres [456 ft] in height), a climb that would take a few minutes to complete, allowing the passengers to contemplate their life.

[10] Sequoia Nagamatsu's novel How High We Go in the Dark, published on January 18, 2022, prominently features a euthanasia roller coaster for children afflicted with an incurable plague.
