A wingsuit pilot experiences line twists that lead to a cutaway. The reserve snags on the rear-facing GoPro, which delays and further complicates the reserve deployment until the GoPro mount breaks. If this happened at a much lower altitude or sub-terminal speed (think BASE), the pilot chute may not have generated enough drag to break the camera mount and this malfunction could've been fatal. The main lesson to be learned is that regardless of how big or small your camera(s), the mount placement should never interfere with the deployment of your main or reserve in any direction. Video is not worth dying for.The skydiver who graciously shared this video with us has since switched to a safer/low profile camera setup. Please check your gear people.
