Sarah Andrews of Alaska visited Disneyland in December of 2017 and was riding Space Mountain when the ride malfunctioned in some way, forcing Andrews’ ride vehicle to be diverted to a maintenance tunnel.
The tunnel was, like most of Space Mountain, dimly lit, which led to Andrews “violently” striking her head.
While exiting the vehicle, a Disneyland cast member reportedly told the guests to look down and watch their step, but did not warn them about a low ceiling.
