The female victim was riding a galloping horse adjacent and parallel to the runway as the pilot was performing a series of take offs, landings, and touch and goes. This had been arranged by the victim for a professional photographer to take pictures of her, as she and her horse were passed by the airplane overtaking her from behind. The horse and rider were on the right side of the runway, between the photographer and the runway. A witness reported that on the sixth or seventh pass, a 'popping sound' was heard as the airplane passed. He 'assumed' that indicated contact between the airplane wing and the victim's head. He also observed the rider, who 'appeared to be unconscious,' fall off of the horse as it continued to run. The airport manager did not see the mishap, but he heard a 'loud thump.' The photographer's written affidavit stated in part that the airplane 'veered off course and struck Jamie which in the back of the head.'
