As a new wingsuiter, Eric made a rookie mistake. He deployed his main parachute with an asymmetrical body position while flying too fast, which resulted in line twists. A simple mistake. As he tried to kick out of the line twists, the canopy went into a dive and he resorted to his standard emergency procedures. Without an RSL, he ends up deploying his reserve in a head-down position while flying on his back, but it was a clean opening and he landed safely.
At the very least, this video is a good example for maintaining altitude awareness and making the right decision (to cut away) with plenty of altitude to spare.
Thanks for sharing, Eric.
