Without Ed Fatinger’s engineering help, the Dyrdek spiral would not have happened within the time and budget constraints we faced. Having essentially copied Jay Milligan’s ramps, we learned on the first attempt that there were major changes needed to facilitate the 50 year newer platform of the Sonic and in all truth, we should have gone to Ed from the start rather than go with JM’s design. 7 more attempts with major modifications to the ramps before each new try gave us something we felt that a performer like Rob could safely attempt. We warned Rob that speed was critical as to bear-hug the steering wheel as it pulls very hard to the right as the right front wheel is on the final stage. The data suggested that Rob went about 3 MPH too fast and it was apparent in the frame by frame video playback the car had steered too far to it’s right which changed the flight path making the touchdown more of a miracle than a landing. Much credit goes to Elia Popov and his team at JEM Effects, as well James Smith and Eric Matuschek, the co-designers-fabricators and stunt performers who were the key parts of my team. Thank you for the terrific article, it was and is a very proud accomplishment for us and James has gone on to do a very nice landing in a Crown Victoria on another project. Jimmy Canton-Kolsto did more Astro Spiral Jumps than any man in history while working for Jay Milligan. We flew him from Iowa to LA twice to educate us and to see Rob off on his terrific performance for Chevrolet. Jimmy and I email jokes to each other daily. He must be 88 by now but hero’s like him are hard to come by and good to keep.
