Today's comic is already pulling hard at my suspension of disbelief - this is just not how climbing/ abseiling accidents happen. Unless you're a complete idiot and really careless (and I don't like to think that of Alice, who I think does this professionally as well, because amateurs usually don't climb turbines) you will check your rope for structural weaknesses and, especially if you're a professional, regularly exchange it for a new one even if no tears or frailties can be seen. Since one is today able to produce extremely reliable ropes, this makes today's scenario in the comic very unlikely - unless it is a special feature of the Alice Grove universe that they can't produce structurally sound ropes.
The climbing accidents that do happen are mostly due to people doing their knots wrong, forgetting to tie themselves in properly due to being distracted (!) or not being able to use their abseiling equipment correctly, not to speak of them falling on rocks/ against the wall, avalanches and the like, which can't happen when climbing a turbine.
