umm are asking what to the straight air?

thats cable dude. the line turns the cornner there. he rides past the corner bouy loads the line and waits for it to elevate him and pull him around the cornner. does look kind of freaky but you see it all the time.

Jay is referring to when he loads the line with the rope in-between his legs. Pretty crazy stuff...

^andrew nailed it, I didnt see that the first time.

haha- reminds me of a swinging carousel at a fair.
