“ Stupid drone eating tree!!”
******************************
Yes, such drones would not be able to fly home with the trailing cable that was unreeled and left in its flight path. So their current utility would be limited to one-way kamikaze missions where the target’s general position was already known (perhaps by “spotter” surveillance drones). Adding a fiber cable disconnect ability would give it potential to be homed.
And then you would have fiber optic threads draped everywhere. Not sure what problems that would cause.
Somewhere between “Uggh spider web, where is the spider now?”
And heads being cut off when they run through the cable without seeing it.
