" did the rope part though?"
Good grief, Wellwell, you're right.
The RNS only told us the rope 'failed', not that it actually parted. That's just an assumption we're all making.
I've seen rope (both SWR and fibre) 'fail', but the problem was recognised before anything actually fell. Or the rope actually broke. In fact, seen it in SWR a few times. Example, a crane lift, where the operator picked up, but the load didn't budge. What was happening was the crane wire unravvelling (old, well-worn wire, admittedly).
Fibre? That was amusing. On a 17m pitch in a Pyreneen cave. Luckily three of us were already at the top. It was a well-travelled route, we'd been going up and down it for a week, and we knew it was getting well-worn. Number four set off up, for a couple of metres, then slowly decended to the floor again. He tried to continue, but with no movement. Further up, the rope's outer sheath had finally completely worn through, and all he was doing was dragging down the outer sheath over the core!
Poor bugger had a one and a half hour wait while one of us at the top continued out and back to camp for a new rope to re-rig the pitch, (something which should have been done a couple of days earlier, really).
Not suggesting BW's buoy pull-in rope was in that bad a state, but yes, a rope can fail without actually parting. Beware assumptions.
