SuperSonic (cancelled roller coaster)

History
In 2000, SEGA Universe near San Jose was under construction, and they needed a star attraction, so they contacted Intamin to build a 200 mph, 175 ft tall launch coaster called SuperSonic, themed to Sonic the Hedgehog, the coaster was to go 200 miles per hour in 5 seconds, becoming not only the fastest coaster, but the fastest acceleration on a coaster, beating Do-Dodonpa by around 6 months once the park opens, due to the sheer force, people were planned to have required to wear protective goggles (nicknamed as Chaos Eyewears during development) to cover their eyes, the coaster would also have 5 inversions, including a loop that has the second most G-force of any vertical loop of all time behind the Flip Flap Railway coaster of the 1900s.
