Actually in DL/CA it's called "Soarin' Over California," but in the Florida park they are leaving off the end.
Once again I will vouch that Soarin' is awesome. It's my favorite "ride" to date because I just can't believe how intense it is for a ride which barely moves.
For spoilage it is best described as a hanglider simulator, where you sit in seats suspended from above and are thrust forward into an IMAX-like theater. The seats move in coordination with the movie on the screen to give an uncanny feeling of flight. Wind machines and scents to go along with the scenes just make it that more intense.
