A local woman who had just gotten off the Mission: Space ride at Epcot Center in Walt Disney World yesterday, felt a tingling in her arms and hands while talking to friends and then suddenly fell from a standing position, hit her head, and slipped into unconsciousness. She was taken to the hospital and later released in stable condition. In the past 13 months, two people have died on the spaceflight-simulator that spins and subjects riders to twice the normal force of gravity. A 49-year-old woman died in April after the force of the ride caused her brain to bleed, and a four-year-old boy died a year ago due to a preexisting heart condition exacerbated by the centrifuge. Since that time, paramedics had to be called to the ride to treat 194 people, including 25 unconscious, 26 with respiratory problems, and 16 with irregular heartbeats. In May, a tamer version of the ride was installed that lessens the G-force.
