A diving friend of mine was a German paratrooper. He once spent over 24 hours hanging in a tree near Sennelager after his main chure roman candled and the reserve when he pulled it, wrapped round the main. He fell very fast and a tree broke his fall. The delay in finding him was due to the rescuers not realising he fell vertically and didn't drift downwind and because they didn't hurry as they didn't expect him to be alive. He was completly unharmed and jumped again two days later!
