[quote=Anonymous][quote=Anonymous]Mechanical engineer here. If the velocity is such that a rider cresting the top of the intermediate hill would be launched on an upward trajectory (in other words, he has sufficient upward momentum to overcome the gravity that would push him back down the slide, or "get air"), and the only thing that was supposed to keep him in the raft was the Velcro harness, then why wouldn't the raft itself be launched upward, too, with all the other occupants, on every other ride? I don't think it's held down by anything.[/quote] It's not held down. The raft just fits in the chute. There's nothing holding it on to the slide. Have you seen the video of the early tests? The raft comes right off the top of the second hill and flies about 20 feet into the air. [/quote]
