Chitown said: I don't think B&M had a problem agreeing to the North America exclusivity as I don't see SF, CF, or any other parks in this country beating down the door of B&M for a dive machine. These have been around for a number of years and Busch is the only company in this country to purchase them.
Right. It's not as if Busch had to twist their arm to get them to agree. Since Oblivion debuted in 1998, how many U.S. parks were really interested in a dive machine before Busch built one? Not many, it seems.
In airplane lingo it may be a Half Cuban Eight but in roller coaster terminology that inversion is typically called an immelmann: The maneuver starts like the first half of a traditional vertical loop. When the train is near the loop's apex it will be inverted and heading back in the direction it entered. Rather than completing the loop in the traditional way, the train rolls on its axis becoming right-side-up while simultaneously turning away from the loop. The result is the train exiting the maneuver in the opposite direction it came.
