I was just taking a final look at the original photos Saul and I took of the day and had skipped past quite a few because they were blurred.
Upon taking a closer look I realised that three were taken on the final descent to Butter Tubs.
Saul had the camera in sport mode and had taken three shots in very quick succession as we came down the hill and has inadvertently captured the seconds after Paul hit the barrier. In them you can see a cloud dust moving to the left of his car.
cjj has obviously pulled up and is just out of shot from this angle behind the wall. I have zoomed in on the middle one of the three photos
