That can't be right. It's true a tab releases a clamp that grabs onto
the cable, but that clamp ensures that the car does not slide along
the cable. When the clamp is released the car needs to be lifted up
off the cable, as is done in the station. (The cable goes down, and
the car rolls along a track.) If the clamp was inadvertantly released
along the course, the car should not drop from cable, as the weight of
the car alone should have kept it on the cable, though it could
possibly slide. The car has to be lifted up off the cable in order to
be released. Something else had to cause that car to fall. I heard
that it had to do with the tower roller assemblies.
A faulty clamp is what caused a problem at Kings Island when it
started to rain. One car lost its grip on a wet cable, but for reasons
listed above did not fall off. It happened shortly after leaving the
station when the cable is at a steep angle. Another car ran into it
but neither fell. A ride attendant e-stopped the ride, and riders were
stranded for hours in a storm. KI removed the ride the following
season.
BTW what does any of this, even the first post, have to do with the
topic 'Pacific Ocean Park'?
