As I mentioned on the Smiler thread, I have ridden The Big One many times since the first crash back in 1994, but I look over my shoulder every time I climb the lift hill to double-check that the other train made it back to the station OK - then I can relax and enjoy the ride.
I rode the Space Invader after that lad fell out.
I ride the Grand National, yet I remember that grizzly newspaper article about the youth who got pushed onto the coupling between the cars and went round a full circuit with his mates hanging onto him from the back bench of the car in front. That was in the days before the platform gates, and happened during the Illuminations when the platform was packed.
I still rode Nemesis this one day, despite there being a hold up in the queue - turns out a guy had had a heart attack and died on the ride.
I rode Raging Bull at Six Flags Great America not long after that girl choked to death on her bubblegum during the ride.
I've been on the Runaway Mine Train at Alton Towers since the decoupling accident.
I've been on the Rapids at Thorpe Park after someone fell out and lost their ear.
I rode Indiana Jones and the Temple of Peril at Disneyland Paris after (oh yes - shhhhh! No-one knows about that one...).
I've been on Treetop Twister at Lightwater Valley since the accident in which one person was killed when two cars collided.
I've ridden the Ultimate at LWV after the trains collided (one train failed to make it up the lift hill into the station after the other train had left the second lift hill). I was even riding The Ultimate when a bearing came loose, leaving the car behind flopping from side to side - I waited until they fixed it and I was back on the next ride.
But you know what? I probably will never ride The Smiler. I didn't feel the urge to go to Alton Towers to ride it before the accident, and I certainly don't feel the urge to ride it now. But then that's a whole other story about me and Alton Towers ;-)
