that wasnt intetional, thats a classic "zipper effect"
the problem is when you take a fall you run the risk of zippering, the tension the rope puts on the protection devices makes them pull in ways the climber did not expect and thus causes them to pull from the rock, once one pulls, it creates that much more impact on the device below making it fail..the effect duplicates until it either stops pulling protections..or you hit the ground.
Osman was VVERY lucky a device finally caught him. If you watch the video you can see in the rope the many little devices in the rope as they get pulled from the rock, they look like little danglingly thing on the rope...those are the cams he put it as they pull ouut of the rock.... he was crapping himself for sure.
Ive never had this happen thank god...id probably scream like a little girl all the way down.

Hey cool! Finally a really cool climbing video without Dan Osman. I really wish I lived closer to a crag.

Comment hidden because you are ignoring dag. (show it anyway)

RIP Dan Osman, but I think that makes my point pretty nicely.

FYI, Mr Dan Osman is dead.
