Mondo Knows Facts

Kingda Ka was the tallest roller coaster built

The 139 metre tower at Six Flags Great Adventure opened in 2005 Kingda Ka in New Jersey launched riders to 206 kilometres per hour and climbed a top hat element 139 metres high, making it the tallest and fastest coaster when it opened in May 2005. It used a hydraulic launch rather than a lift hill. The ride closed in November 2024 and was demolished the following year, so its records belong to that period. It sits in Mondo's records & extremes collection, one of 200 facts that each trace back to the reference below.
