Was it the coaster's fault? I suppose. I mean, it obviously had a hand in it, however the guy had heart problems to begin with, and you just don't take those kinds of chances. The ride wasn't faulty. In fact, it was closed for inspection and 2 hours later it was running again.
Anyway, my family has a history of heart disease and heart problems - my dad died from it.
I'm telling you now, for the fucking world to see, that if I ever die on a rollercoaster from something like that - I took that chance, and it was my fault for doing so. I knowingly ride these things with the knowledge of my physical health, and that's just the choice I make. So yeah...just in case.
