I just came across what looks like a video sequence of a possible board leash impact, a fairly impressive one, involving Peter Trow presumably in the Gorge. It would be good to confirm details of this and while we are at it, find out if Peter was injured during the impact. Hope not! Given the 40 to 50 ft. horizontal board flight I imagine the force of impact would have been quite high IF the board connected with him. He may have lucked out with the board hitting the water over him as he fired in deep after flying a good distance through the air.
under "Videos" and "Wipeout" and the second video from the right.
