Lower the unobtainium cable! Lower it at an [itex]\epsilon[/itex] short of
lightspeed if you like. How long will it require for an external
observer to see it finally penetrate the event horizon?
You cannot peform your experiment until you've threaded the event
horizon. You cannot thread the event horizon in a finite time
interval as viewed by an external reference frame. No conundrums
obtain.
