The fierce Kingda Ka is simply the tallest, fastest roller coaster on Earth. This remarkable thrill ride breaks all world records for coaster speed and height, zooming from
0 to 128 mph in 3.5 seconds and catapulting you 45 stories into the sky.

Get propelled horizontally at 128 mph via hydraulic launch
Hang on tight as you shoot 90 degrees into a quarter-turn
Blast 456 feet high, then plunge vertically into a 270-degree spiral
Experience weightlessness as you swoop down a valley and up a 129-foot camel hump
Kingda Ka is a roller coaster located at Six Flags Great Adventure in Jackson Township, New Jersey, USA. At its opening on May 21, 2005, it became the tallest and fastest roller coaster in the world, claiming the title from Top Thrill Dragster at Cedar Point. The train is launched by a hydraulic launch mechanism to 128 miles per hour (206 km/h) in 3.5 seconds.[1] At the end of the launch track, the train climbs the main top hat tower reaching a height of 456 feet (139.5 m).[2] Due to aviation safety concerns, the tower is equipped with three dual strobes: two mid-way up, and one on the top.

History

Kingda Ka was officially announced on September 29, 2004, at an event held for the media and enthusiasts.[3] It was revealed that the ride would become "the tallest and fastest roller coaster on earth", reaching 456 feet (139 m) high and accelerating up to 128 miles per hour (206 km/h) in 3.5 seconds.[4]

On January 13, 2005, Kingda Ka was topped off at its 456-foot (139 m) height, finishing construction.[5] A crane over 500 feet (150 m) tall was used to hoist up the highest track piece for the ride. Just approximately four months later, Kingda Ka opened to the public, media day being two days before, on May 19.

Kingda Ka was originally supposed to open on Saturday, April 23, 2005, but on April 18, 2005, Six Flags announced that Kingda Ka's opening would be delayed; media day would have been on April 21. [6] Before Kingda Ka was built, Cedar Point's Top Thrill Dragster was the tallest and fastest roller coaster on the planet.

During a test run with no passengers on June 8, 2005, a bolt failure caused damage to the launch cable resulting in closure of the ride until August 2005, and the reconfiguration of the line area.


Major malfunctions
On June 6, 2005, less than a month after its grand opening, a bolt failure caused the liner inside the trough that the launch cable travels through to come loose and create friction against the cable. The friction caused the train to not accelerate to the correct speed. The rubbing of the cable against the inside of the metal trough caused sparks and shards of metal to fly out from the bottom of the train. The engine, as it is designed, attempted to compensate by applying more force to the cable to attain the 128 mph (206 km/h) launch speed.
The brake fins—metal fins attached to the underside of some roller coaster cars that slide between brakes mounted to the track[7]—rise up into the braking position on a timing pattern, independent of the launching mechanism. The fins are mounted in steel supports that are connected to actuators that raise and lower the fins into the desired position. There are four braking zones, and each zone has about 24 individual brake fins. The fins actually caught up to the launching train as the timing pattern of the rising fins was faster than the accelerating train. The magnetic brakes began to slow the train in the launch area, and the engine tried to compensate even more, and dragged the train through the brake zones. The catch car released, but the train was still in the brake zone and came to a complete stop at the bottom of the hill.

This malfunction occurred when no passengers were aboard during a test run. No injuries or deaths occurred. Damage occurred to the launch cable (frayed and needed to be replaced), engine (minor routine damage to seals), and brake fins (many needed to be replaced). The brake fins in the launch section are mounted in such a way to keep fast moving trains from moving backwards into the station, but a fast moving train being pulled forwards caused an unexpected stress on a number of fins that bent them forward. Not all of the fins needed to be replaced, but there were more damaged brake fins than Six Flags had replacements, and extra brake fins had to be specially ordered from Intamin. In addition, Kingda Ka had to be re-inspected. Kingda Ka started testing on July 21, 2005. It reopened on August 4, 2005, with the line modified so that it no longer ran under the launch track.[8] The dark blue train was being launched when the malfunction occurred. It was used for the rest of the season, but major problems requiring replacement parts were discovered when the train was inspected during the off-season. Consequently, this train remained disassembled throughout the 2006 season.


Ride experience
After the train has been locked and checked, it slowly advances out of the station to the launch area. The t

A Lego brick built derivation of my Ford Model A (1927) Deluxe Coupe 'Grandfather' design.

This model has taken a dark blue roof design (due to part constraints) and includes the stretched 30.4 tyre to cover the Lego Medieval cart wheel.

Included are miniland Grandpa and Grandma figurines (along with their minifig great-grand children), proud of their classic Model A Ford.

This car is modelled on the Model A owned by my wife's late grandfather Lloyd. A lovely car to ride around in, but a bit vulnerable with your head bobbing around in the breeze back in that rumble seat.
