Wouldn't have wanted to wait 2 hours to get on it, though. Wasn't THAT cool.
It was indoors in the main building that was mostly shops -- tucked into a corner. If we hadn't randomly walked by it, I would have never seen it.
Test Track was, though, and other than the fact that it had technical difficulties (forcing us to come back), it was pretty cool.
The test track always has had technical difficulties. When I've been there, it seems to be shut down about 50% of the time.
I forgot one other thing at Epcot: Soarin' It's in "Future world":

You enter the room and take a seat. Then the seat assemblies lift up and pivot, so they are vertical -- every person has a front-row seat in front of an IMAX screen.
The screen shows a video from a hang glider in a series of scenes. The seats shift slightly on turns, and fans create a breeze -- as if you were under the wing/canopy yourself.
An awesome experience, but a very long wait the one time I did it.
