Yeah, I hadn't heard about that one before. Sounds legit, but very unlikely. Trapping a draw upside-down on rings and hangers has also led to many instances of failure, including one in the Grampians which was written up on chocky, and another in germany where a well known nati climber ws belaying, and the climber ended up in a wheelchair.
In short, draws getting trapped off axis and unclipping or breaking is a failure mode common to all bolts. |
