I e-mailed Russ and also the Quicksilver team some months back. I've yet to get a response from Quicksilver...
Wicks' project manager e-mailed me back. When I initially wrote him, I pointed out that Russ had gotten the "stock car" record at Bonneville, but had yet to make any WSR announcements/attempts/etc. I got a reply which basically said that until more $$$ floats their way, they are going to focus their efforts elsewhere.
No bucks, no Buck Rogers
