There are two new roller coasters opening this summer with a thrill factor rating of 5, according to the American Coaster Enthusiasts. A 5 means that you're in for a hair-raising treat that is unique from other coasters' offerings.

The Flying Turns is a bobsled ride of sorts. Styled after a roller coaster that was popular in the 1930s to 1950s, this ride is a remake. Two people sit with one in front of the other in one car that is joined with four others. The cars then zoom down a wooden track that circles in various configurations for two minutes. The thrill partly comes from it's rarity. This is the only coaster like it. Head to Knobels Amusement Resort in Elysburg, Pennsylvania to try it out, although, I'm not sure if it's open yet. It is supposed to open this season though.

The other top thrills coaster, Griffon, is found in in Busch Gardens Europe, Williamsburg, Virginia. The park's Web Site has a clip advertising it with a horror film type voice that finishes the description with "The only way down is face down." It's also described as "the world's tallest, floorless dive coaster." Just look at the photo. The dive part comes from the 90 degree angle decent. The floorless part might be because you sit with your legs dangling. Somewhere along the three minute ride there are two inverse loops that are patterned after the stunt of a World War I German fighter pilot. Leave your sunglasses behind.

The other top new coasters to open this year, according to the enthusiasts, are: Tony Hawk's Big Spin (see post) Thrill factor: 2; Mystery Mine (see post) Thrill factor: 4; and the Maverick (see post) Trhill factor: 3.
