World's fastest and tallest rollercoaster to drop over cliff with top speed of 156mph

Rollercoaster fans are about to witness an adrenaline rush like never before following the announcement of the world's fastest and tallest rollercoaster - with a top speed of 156mph.

The most scary feature will no doubt be the massive 640ft drop over a desert cliff.

The epic project was presented at the International Association of Amusement Parks and Attractions Expo earlier this week.

"I will never forget the moment when I was standing at the edge of the 200-meter-high cliff on the Tuwaiq Mountain in Qiddiya, looking into the valley and imagining the creation of a future record-setting roller coaster," Daniel Schoppen of Intamin Amusement Rides, which is working on the coaster's design, said in a statement.

"I knew that exactly at this spot, the Falcon's Flight will dive down along the cliff, ending in a unique, exhilarating 250 km/h (155 mph) proximity flight close to the ground.

"The worldwide unique setting and heights such as the natural cliff will enable us to design an architectural masterpiece in steel."

“Rollercoaster fans around the world have been eagerly anticipating this ride since it was announced as there is nothing quite like it anywhere else,” added Qiddiya’s Chief Executive Officer, Philippe Gas.

“Now we are in the design stage with the experts at Intamin and the engineering team at Six Flags, the excitement is building!

"Falcon’s Flight will dominate the skyline at Qiddiya weave all the way around our destination, right out of the theme park, up the cliffside, and down the cliff face.

"The greatest drop of any ride in the world.

"It won’t be for the fainthearted.”
