Kingda Ka holds the title for the world's tallest roller coaster. For nearly a decade, it was the world's fastest roller coaster. It reaches speeds of 128 miles per hour (206 kilometers per hour). It is 456 feet (139 meters) tall with a 418-foot (127.4-meter) drop. And if that is not enough, the train rolls 90 degrees on the way up and 270 degrees on the way down!
