PWCHH!!!
The sound of a cable snapping on an amusement park's thrill ride -- right before it severs your feet! Screams ensue, and similar rides are shut down nationwide.

"I seen the car go up. Then, like, the cable broke, I heard -- pwchh -- and I heard a lot of people screaming." - Chris Stinnett describing June 21st 2007's Superman Tower Of Power disaster at Louisville's Six Flags Kentucky Kingdom.
