Thanks for the model Mikl. It shows that failure is possible in bending at just bodyweight! I'm going to think twice before buying those uber-lightweight biners I was looking at.

I totally agree. I did mention in an earlier post that there are a number of factors which would prevent the climber feeling the take in the rope. But he said “absolutely no take in the rope when I heard a snap”, which is physically impossible. Thus proving the lack of reliability of witnesses.
