This is an interesting style of coaster. It has been named a Spaghetti Bowl coaster because of it's track layout. There are multiple outdoor versions, and 2 enclosed versions. I have ridden one of each. Flight Of Fear at Kings Dominion and Jokers Jinx at Six Flags America. When these coasters first opened I didn't really care for them at all. They had shoulder restraints and you spent the whole ride with your head banging against them. However after too many complaints, they finally took out those restraints and replaced them with a lap bar making it a much more comfortable and fun ride. The enclosed version (Flight Of Fear) is pretty cool. The line area is set up like an Area 51 type deal. While on the ride, it is mostly dark with some colored lights. It's interesting because there are times where you cant tell if you are upside down or not. However, I prefer the outdoor version, the dark effect on the indoor is cool, but I think its more fun to see whats going on.
