Report from the Russians- gusting winds changing from crosswind to tailwind measuring 18-22mph (8-10m/s) the throw was clearly visible as a forward throw immediately after exit. The PC was inflated prior to the exit, and the jumper was not really able to throw. It seemed like right after the throw, the PC was blown behind the jumper. The PC was already inflated at the time of exit as he was holding it by the mesh. It was most likely unintentional as the jumper was experienced and new to throw instead of letting go. The container opened really low, he impacted right before complete linestretch, with lines partially out. Witness Speculation : exit - inflated PC - sudden gust of crosswind blows the PC behind the jumper - jumper tries to change body position as he realizes something is amiss - the PC clears the burble, but it's too low.
