Based on video and eyewitness accounts: Jimmy was the 3rd jumper in a 3-way wingsuit exit. Jimmy exited head high, and remained too flat to begin immediate and efficient flight. He only achieved efficient flight after a 7 second period of freefall in a near-stall configuration. (Jimmy flew for 29 seconds total, popular reports stating that he "hit a ledge" or "went head down" are untrue). The remaining 22 seconds of Jimmy's flight occurred just above the snow in the couloir at the bottom of the canyon, at an altitude that was too low to pull safely. After matching his glide path to the couloir in the bottom of the canyon for 20 seconds, Jimmy deployed his pilot chute. In the outside video, it is possible to see the pilot chute and canopy top surface deploy. Immediately after canopy extraction, Jimmy impacted the couloir in a head first configuration. He had 103 BASE jumps, with approximately 45 of them being wingsuit, prior to this incident. He had more than 700 skydives.
