I agree that these rides are designed with safety being the number one concern. However, if there were to be a severe failure, the potential for death and injury is huge. As a former ride op, people used to always ask me "Can that coaster get stuck upside down?" And I always said "Impossible". But in the past few years, there have been major mechanical/structural failures that resulted in 2 coasters grinding to a halt in the top of a vertical loop. Now, the chances of this happening are very, very small. But it happened. Of course, one can argue that it's not the designer, but more so the park, who is responsible for maintaining these rides. So maybe Vekoma and Giovanola do have a fool-proof system of redundancies built in. Will those measures ensure the same level of protection 5-10 years from now? Who knows. Depends on the park. But regardless of how redundant the tilt mechanism is, there is always the potential for failure. I've seen things on brand new B&M coasters that technically cannot happen! We're talking about things that the manufacturers would probably say, "That's impossible". And I wouldn't have believed it myself, had I not been there. But there are humans behind those twisted structures of steel and wood, and mistakes will be made. Is it worth the potential risk? I guess the parks installing these rides have to ask themselves, are we prepared to handle the repercussions of ""dropping a fully loaded train". Because no one can say, it won't happen. And what are the repercussions of dropping a train 100ft with 20-something guests? Depending on the size of the park, that kind of thing could put you out of business. Has there ever been a loss of life that big in a theme park? I know some SF park had a fire years ago that killed a significant amount of people, but 20-30 peeps? That's a big deal. That would certainly make international news. It would be very difficult for any park to recover from that incident. Legal fees, horrible publicity, lawsuits, lawsuits, and more lawsuits. The guys that got stuck upside down on the Demon are suing and they weren't even seriously injured. Lots to think about, I suppose. Would I ride one? Depends on the park maintaining it :) My 2 cents - epc0t
