Follow-ups:
I was Their When The Trains Collided. It was Scary And Horible. I want to make clear that this was not an ride operators mistake, like the previos person suggested. I waro At Six Flags Magic Mountain, and Operate The Attraction ,THE RIDLERS REVENGE. All rollercoasters are moniterred by a computer with a check and balances procedure. Meaning if theirs an error of serios concequences,Like trains Crashing, the computer will administer the emergency breaks and stop the ride,(train) at its block breaks Section. I just think is unfair people pointing fingers while not knowing the Truth. -- Reported on August 17, 2005 by Leo Guardado.

Heya... just to second the earlier comment. In these days, rides are NOT controlled by operators. Ride operators often have accsess to only one or two controls, one of which being the emergency stop. When you go through training, you are told to ONLY press that switch in two occasions. An earthquake, and if there is a guest or employee ON THE TRACKS. Ironic as it may sound, pressing the emergency stop, on some rides, can actually cause more harm than a collision of two trains. I am 19 years old, and im an EMT. My first job was at six flags magic mountain, working on the ride called "Freefall." ... If you were to press the Emergency Stop button at the wrong time, you could theoretically kill, maim, or paralyze the passengers of that ride. The force would be equivalent to driving a Geo into a a solid brick wall at 55mph. -- Reported on August 25, 2005 by Mike G...
attractions like california screamin' accident have very little to with operator errors because like the other person wrote, they have limited access to the real functions of a ride like that. Even if people think that someone could have stopped the accident from happening they are wrong because its like a car accident Fido, even when you slam on the brakes it takes time to actually get something in motion to sctually stop, it is easy to point a finger when you ignore physics. -- Reported on September 21, 2005 by christina medina.
Agian, Many, if not all park guests are unaware of a ride opperators skill. Unfourtuantly Kevin was injured on the CA rollercoaster. But like the two other Ride Ops allready mentioned... This accidented WAS NOT RIDE OPS FAULT. I train ride ops at a local themepark and am well aware of the procedures of launching vehicles. The attraction control is simaler to that of air trafic control. There are monitors, buttons and alarms. IT IS IMPOSSIBLE to launch the two veichles at the same time. Translation: Until train A cleared the launch and the drop and passed the second brake pad, train B couldnt be dispatched. the computer would not allow it, its like trying to start the car without turning the key. It was clearly brake failure and was inevitable. Estopping trainB before it collided with train A would injure the riders just as much as the actuall colicsion did, and it would injure the other riders as well. Besides the fact, all guests take the risk of injury or even death when the purchase their ticket, read the print. IF you have not trust for Ride Ops, you have no business being in the park. Ride Ops are virguerosuly trained to operate the ride in all conditions, we are people too. -- Reported on September 30, 2005 by Keiko Ariyill.
