So this is taken from Screamscape today, this sounds serious and could lead to many complaints, it does seem strange:
2014 - Zumanjaro: Drop of Doom - Breaking Update - NOW OPEN!! - (7/8/14) While Six Flags Great Adventure managed to open their new Zumanjaro: Drop of Doom thrill ride this past weekend, built onto the side of the massive Kingda Ka coaster, all is not well in the park right now… or with either attraction. For reasons than I find hard to fathom, the state of New Jersey has put some serious restrictions on the operations of both rides, that is simply causing more harm than good. So be fore warned… if you intend to ride either of these… get ready for a LONG wait time.
The short story version is this… the state has decided that Six Flags can not run both of these rides at the same time, and is rumored to have gone so far as to require that the park link the ride control systems of each ride together so that there is no chance of it happening. Why? Because they are worried that either on purpose, or on accident, that loose objects from the riders on Kingda Ka may go flying into the riders on Zumanjaro: either horizontally during the launch towards and up the tower, or could fall down on them from the top of the tower. It seems that they felt the roof panel on the top of the Zumanjaro cars provided inadequate protection and the only way to protect the riders is to simply not run the rides at the same time. While it is a slightly different layout, apparently the lack of any problems with the similar Superman / Lexx Luthor combo ride at Six Flags Magic Mountain was not enough to convince them otherwise.
The resulting bit of insanity has caused very long lines as a result so far on both attractions as I’m told the operations go something like this. While Zumanjaro sits empty and idle, Kingda Ka will load and launch two trains back to back. Once they return to the station Kingda Ka goes into a hold and only then are riders allow to load into the Zumanjaro seats and then dispatch into a ride cycle. Once they land again and are removed from the car, Zumanjaro goes back into a hold mode and Kingda Ka can launch two more trains. Rinse… Repeat… and watch the faces of the park guests start to contort as the lines get longer and longer.
I can only hope that clear heads and look into this and solve this issue, as rides criss/cross over and under each other all the time and they’ve never been banned from running at the same time. The state obviously had no problem with El Toro running over the top of Rolling Thunder for all those years, so why the headache now?
