According to RCDB, you're right... Circumstantially.
If the original poster is still lurking around unregistered, just know: our Stunt Coaster is by far in the best condition of the three. By far. Kings Dominion's Italian Job Turbo Coaster (that was really its name!) stops on the midcourse brakes where there are no flames, no sound effects, no helicopter, nothing. You just sit there and listen to the clicks where the pilot lights would normally plume. Wonderland's doesn't even stop on the midcourse brakes if it doesn't have to, cruising right on through (why should it stop, after all, when none of the effects work?).
When I was there this past Friday, there were sound effects, along with the lights lighting up where the bullets are shot out of the helicopter. The only thing missing was the explosion. It also has a splashdown, whereas King Island's was taken out.
But I did manage to see a roll-back on it at KD while I was there also. While, knowing that it is launched uphill and is completely possible, I had never seen it to be an issue. Have any of us here ever seen this happen at KI?
