    A drill and reel could wind up the fiber if the drone has exploded and the cable is loose. If the cable is still attached to the drone, it could send a signal to a device at the end to cut/blow up the fiber attached at the drone’s end.

    Guessing it’s impractical as they’re not doing it.

      that works as long as the cable is on perfectly flat surface and not tangled up in any way at all.

          It’s not even just 1/2 mile. I read an article recently that 15km spools are already in use and 20km spools are actively being tested.

            Is the tensile strength anywhere close enough to reel it back? I assumed the spool is carried by the drone, not dragged from the source.

            It’s a really interesting/terrifying technology. But it’s gonna a be a mess to clean it up.

              Tensile strenghth is definitely enough. Ive used fiber to tow vehicles before in a pinch. A single strand takes a surprisingly higher amount of force to break than one would expect. Good luck pulling a window pane in two…
