The Euthanasia Coaster is designed to thrill the hell out of its passengers just before it kills them.
Each inversion would have a smaller diameter than the one before in order to inflict 10 g to passengers while the train loses speed. After a sharp right-hand turn the train would enter a straight, where unloading of bodies and loading of passengers could take place.
The Euthanasia Coaster would kill its passengers through prolonged cerebral hypoxia, or insufficient supply of oxygen to the brain. The ride’s seven inversions would inflict 10 g on its passengers for 60 seconds — causing g-force related symptoms starting with gray out through tunnel vision to black out and eventually g-LOC, g-force induced loss of consciousness. Depending on the tolerance of an individual passenger to g-forces, the first or second inversion would cause cerebral anoxia, rendering the passengers brain dead. Subsequent inversions would serve as insurance against unintentional survival of passengers.
