If you're planning on flying around Devil's Lake, ND anytime soon, you might want to check in with the FAA—the government is locking down a big chunk of the sky to fire off eye scorching UAV lasers.
The restricted zone will be reserved for drones and drones alone—civilian planes will have to fly at a different altitude, or around the area altogether, which the FAA admits is "vast." So why does any of this matter? Drones are just tiny lil' things, right? And it's not like the they'll be shooting hellfire missiles down into Bismarck. But even something that doesn't explode can be risky in the sky (and down below): the drones will be firing targeting lasers from high altitude, lasers with enough power to be deemed "non-eye safe." How non-eye safe is non-eye safe? Enough that "Personnel working at the [targeting] range will use proper protective gear." It's safe (but not eye-safe) to assume these beams could seriously screw your retinas.
