4-D is a kind of coaster, like X at SFMM (which happens to be the only 4-D coaster in the world). You sit in carts on the side of the track and they rotate 360 degrees.

Launch Coasters Rule!

No eric uehlein it mean that you are a big wuss and don't want to go on the ride. And for 4d mean that 4 mens the times that u chickened out on the MF and d means that u are dumb.

Just Joking Eric

HAPPPPPPPPPY BIRTH DAY!!!!

THE BIG 15

A coaster that runs on a "4th Dimension" (used to for effect). The seats flip forwards and backwards 360o while youre riding it...

and something that doesnt belong on the "Area 51" boards ;)

Thanks for the information. The reason i put it in Area 51 because i happened to hear it discussed about the new ride possibly being in "4D", but as to the description it seems highly unlikely.

i think people would die on it if it was 4D, i know i would

Believe me, the supposed 4-dimensional ride "X", only uses three dimensions. Only math can descibe dimensions greater than three. Oh...math and the Twilight Zone.

Yes Sigma, we know..... its for effect.

I'm sure YOU know. But I was just adding to some of the responses here to try and help Eric Uehlein understand.

gotcha ;)

Here's some sites with many pictures of X.

The list of links on the left has the pictures for X. The other side is Deja Vu stuff.

And why did you post this in Area 51 again...
