During break-off on a formation skydive, this skydiver doesn't get enough horizontal separation for a safe opening, so he tries to create some vertical separation by pulling a little lower. Another jumper opens nearby and his canopy surges towards the jumper who pulled lower, which nearly results in a canopy collision — the jumper who was filming actually had to lift his legs to avoid getting hit by the other canopy. And of course the camera lens had to get fogged up right at the "money shot" of the incident.
Remember to track away at break-off like your life depends on it. Because it does. Horizontal separation is far more effective and safer than vertical separation.
