Kitesurf crash Groene Strand Terschelling

Kitesurf crash Groene Strand Terschelling Kiter on the right jumps unhooked, hooks in and goes downwind. Kiter from the left goes downwind to prepare jump. Both not expection eachother at that point I guess. Just 2 seconds before impact the kiter from the left jumps, i don’t know if this caused the crash or made the impact a little bit lighter. It looked a bit nasty so the ambulance was called but in the end it was hust a couple of red marks for the crashed kiter just below his knee.
