The airtime is some of the most intense airtime I've ever experienced. Back seat on Kennywood's Jackrabbit has nothing on the air Hypersonic produces (not that I consider Jackrabbit any less of a ride, of course ;) )
In spite of that, you're not going anywhere with those restraints, even of you leave yourself a little room...
