Failing
It was an old school solid shaft friend belong to an old school climber whose rack we were using. I ran out of gear to fit the crack and was using any old gear that would place, but that wasnt the problem here... problem is a pair of swages on the inner (inside the crack I mean) (I think) cams popped and then the cam rotated around the two outer cams, popped out of the crack and actually snaked down the rope smacked me as was caught by the next cam below.
