Does anyone have pics of what the collapse of VertiGo had looked like? With the pics that I have when it was there for the 2001 season, it could have landed on 2 of the most beloved of coasters: Gemini and Magnum. The 2002 season may have not been if it landed on a coaster.
I did do some research on how it collapsed and I came up with some wind shearing that came off the Sandusky Bay and the freezing temperatures. It had gave in because each tower was hollow inside and it's like if you put a glass container with water in it in the freezer, the container will explode because of the pressure and the temperature. Did pretty much the same thing except with cold air and a hollow metal tower. I hope that makes sense. *** Edited 10/13/2006 3:23:09 PM UTC by ltparkmaster***

I think they said vortex shedding was the cause of the collapse. It has nothing to do with the air temperature, just the wind currents and the resonant frequency of the tower.
I'd rather be in my boat with a drink on the rocks,
than in the drink with a boat on the rocks.
I was curious what the junk "vortex shedding" was so I looked it up...
Wikipedia says:
Vortex shedding is an unsteady flow that takes place in special flow velocities (according to the size and shape of the cylinderical body).
Vortex shedding is caused when air flows past a blunt structure. The airflow past the object creates alternating low-pressure vortexes on the downwind side of the object. The object will tend to move toward the low-pressure zone.
Eventually, if the frequency of vortex shedding matches the resonant frequency of the structure, the structure will begin to resonate and the structure's movement can become self-sustaining.
Vortex shedding was one of the causes proposed for the failure of the Tacoma Narrows Bridge in 1940, but was rejected because the frequency of the vortex shedding did not match that of the bridge.
