SFGA2001, don't worry, your fine. If it was a Scrambler, your safe.
Do I have a feeling this is going to be like the Goliath Lady? As a recap, Goliath Lady died of a burst anyurism while on the ride. As we all (better) know, anyurisms can burst by coughing, ad often are hard to detect. This results in people dying from them who don't know they have them, because they do things other people do, such as ride a coaster with high G forces.
Blood clots can be the same way. It might have been somewhere in her bloodstream, stuck on the side of the vein/artery. While on the Scrabler at SFMW, it got whacked off (which could also be caused by coughing, sitting, kicking, punching, running, anything) and ended up clogging a vein or artery in her head.
Lets just wait a few days, and the media will be blowing this up, just like Goliath Lady.
