There's a first for everything, right? Who knows...maybe KI is building the worlds tallest, longest, and fastest invert.
I've ridden Alpengeist, and it does not utilize the terrain in a way where it drops into a 60 foot valley, goes through inversions, and then has the speed to get back up and out of it and back into the station.
There's such a thing as a second lift hill.
or perhaps a LAUNCH up out of the valley!!!
