Imagine whizzing through the darkness at Disney World’s Space Mountain, or plunging off a virtual skyscraper at Universal Studios’ The Amazing Adventures of Spiderman. Now combine those sensations with the rumble of blast-off, the pressure of rising G-forces as you soar into space, the excitement of crashing through a terrifying meteor shower, or launching a satellite, and the thrill of roaring safely back to Earth. That’s the kind of virtual-reality experience many people want from the next big attraction at the Kennedy Space Center Visitor Complex, according to a recent informal readers poll by FLORIDA TODAY, the local daily newspaper for Florida’s Space Coast.
