Drones can cost a pretty penny, so make sure not to fly them too near an airport... or a military base. The Pentagon has approved a new policy that gives military bases the right to shoot down or seize both private and commercial UAVs that encroach upon their airspace and are deemed a threat. While details about the policy remain classified, Pentagon spokesperson Navy Capt. Jeff Davis says the new guidance gives bases "the ability to take action to stop these threats (i.e. UAVs or drones) and that includes disabling, destroying and tracking [them]."
