At the bottom end of Geoff's Level 1 AFF jump, he deploys his main and has a bag lock. Watch the video to see how the situation gets handled by the instructor on his reserve side. According to Geoff, the fun wasn't over once the video ends. The reserve deployment released the bag lock, giving him a two-out. Once he cleared the line twists, the canopies formed a downplane. He safely cleared the main, then rocked a downwind landing under his reserve. I'm exhausted just thinking about it.
