The second wingsuit flyer had a camera mounted to his helmet. The aircraft’s left wing had clipped and killed the wingsuit flyer in front. Investigators used the video from the second wingsuit flyer and the aircraft’s navigation system data to recreate the seconds before impact. The PC-6 started to descend even as the second wingsuit flyer jumped, flying a downward slope of about 50°, instead of the expected 20-30°. The following graph shows the expected descent of the Pilatus PC-6 and the immediate descent that led to the collision with the wingsuit flyer.
