It's funny (to me, anyway) to see how many of these stories attribute fairly common ride stops to a ride "breaking down."
The most interesting, unplanned event I've ever experienced while on a ride is, for better or worse, a trip through Space Mountain with its work lights on.
As our rocket climbed the lift hill, the ride stopped for one reason or another. We sat still for a few moments as each of the rockets beyond the lift cleared their blocks and stopped on a midcourse brake. We on the right side lift -- I'm not sure if this designated as side A or B -- and had a rocket stop on the block brakes to our lift's right side. If you're intimately familiar with Space Mountain, you'll know what I'm talking about.
The work lights came on and we had a conversation with those in the other rocket while I explained to my father more about how the ride worked. A few minutes later, some Cast Members came up to the rocket on the brakes and pushed them off into space. I was quite surprised that the rocket needed to be pushed -- usually gravity is enough to get a coaster train off a midcourse brake. A moment later, the lift came back on and we got a complete, uninterrupted ride through Space Mountain with its work lights on.
It was fascinating for me, as a big giant dork, to see more about the layout of the track and structure. It was quite boring, however, as a ride goes and you begin to realize how important sensory deprivation is to the entire experience. Much of the track is straight and you travel very, very slowly throughout much of the ride. While I always understood the ride's top speed was only 28 MPH, riding in the light illustrates exactly how unimpressive that is.
At the end of the ride, we were offered another ride without waiting to set things right and my father and I gladly accepted. That ride was fun for me because I was able to predict the track ahead. I don't know that I'd remember now how the layout is set up, however.
Also, as an aside, Kraken is not near being one of the largest coasters in the US. The 10th tallest height reached by a coaster and the 12th tallest coaster in the United States is 215' tall, 65' taller than Kraken. It is 1217' short of being the 10th longest roller coaster in the US.
