It's 90° straight up. And once you get to the top you'll be plummeting right back down in a 270-degree spiral that is not recommended for wimps. There is very little that can prepare you for a drop of this intensity.

Yes, Kingda Ka, located at Six Flags Great Adventure in New Jersey, features a true 90-degree vertical drop. After being launched hydraulically from 0 to 128 mph in just 3.5 seconds, the train climbs a massive 456-foot "top hat" tower. Once it reaches the summit, the train crests the peak and enters a vertical descent that is perfectly perpendicular to the ground. During this 418-foot drop, the train also performs a 270-degree spiral as it plunges back toward the earth. While the ride's layout is similar to the former Top Thrill Dragster at Cedar Point, Kingda Ka's additional height and the specific 270-degree twist during the 90-degree vertical fall make it one of the most intense psychological and physical experiences in the world of roller coasters. Despite its short duration of roughly 28 seconds, the sheer scale of the 90-degree drop at such extreme heights remains a benchmark for "strata-coaster" engineering and thrill-seeker enthusiasts globally.
