Not my theory about reality..
"A cascading failure is a failure in a system of interconnected parts in which the failure of a part can trigger the failure of successive parts. Such a failure may happen in many types of systems, including power transmission, computer networking, finance and bridges. Cascading failures usually begin when one part of the system fails. When this happens, nearby nodes must then take up the slack for the failed component. This overloads these nodes, causing them to fail as well, prompting additional nodes to fail in a vicious cycle."
and then there's this bit of reality you are apparently unfamiliar with:
Mechanical Structural Failure
Certain load-bearing structures with discrete structural components can be subject to the "zipper effect", where the failure of a single structural member increases the load on adjacent members. In the case of the Hyatt Regency walkway collapse, a suspended walkway (which was already overstressed due to an error in design) failed when a single vertical suspension rod failed, overloading the neighboring rods which failed sequentially (i.e. like a zipper). Properly designed structures either use an adequate factor of safety or alternate load paths (or both) to prevent this type of mechanical cascade failure.[SUP][4]"[/SUP]
I don't even use the term zipper effect.
Lemkin you are a science and engineering denier. Your citations are basically junk science and spam and grasping at strays.
