This comment by the board is most surprising:
23. Three of the witnesses were positive that they had seen twin-tailed ac, not Tornado ac. The board judged that, if they were correct, then the F-15C formation would have had to have avoided the imminent collision with terrain indicated by the last radar plot
None of the eye-witnesses were anywhere near the last radar plot. They were between 6km and 8km to the east and south east of the crash site. This evidence was crucial in supporting the defence theory that the F15s were already engaged in low flying prior to the accident and were last seen on a westerly heading towards the area of the crash site.
