Amusement park disasters have killed dozens since the 1950s—from a 15-year-old thrown from Disneyland's Matterhorn to Action Park's 20-year reign of chaos without liability insurance. This episode explores how recklessness, negligence, and one park's embrace of risk created a legacy of preventable deaths. Mark Maples died at Disneyland in 1964 after standing up on the Matterhorn bobsled mid-ride, hitting a concrete beam and being ejected from the sled, yet the coroner concluded he unbuckled his own seatbelt.
