Same goes for your Skyway experiences. If you rock those hard enough, they can come off the cable. They're just "sitting" on the cable with a small clamp holding them in place. If you swing them far enough, it can be enough to snap that clip.
Thus the reason I will NEVER go on Skyway.
I was once stuck in It's A Small World for ten minutes. If there was anything at Disney that could scare you after a while, it's those IASW people.
