Here's a slo-mo version of papaver's video: http://tinypic.com/player.php?v=33n926f&s=3. It appears that he hit a bump and then slipped on the white line.

Some very graphic photos have also turned up. Don't click if you're squeamish: http://www.daylife.com/search/photos...d?q=jens+voigt

Between Stuey O'Grady's crash (last year or the year before...?) and this, it's so scary to see the tough guys go down. I hope we hear some good news about Jens soon.
