That's why i don't **** with RollerCoasters. Me, my ex, and his nieces and nephew got stuck on one at Great America. I was so ****ing pissed cause i told his dumbass i didn't wanna get on in tha first place
1. This isn't a roller coaster, that's a Super Loop ride. Similar concept though.
2. This clearly happened because there wasn't enough momentum for the train to make it all the way through, but it was too far up to go back down the other way. Basically it was perfectly balanced. This does happen, but the chances of this happening are lower than getting into a car accident.
