Rumors are swirling that Six Flags Great Adventure's Kingda Ka roller coaster is closing, and fans are outpouring love for the world's tallest thrill ride.

Kingda Ka, the world's tallest and fastest roller coaster, has been retired along with the Green Lantern roller coaster as Six Flags Great Adventure makes room for two new roller coasters at the New Jersey theme park.
