While the U.S. government has come under criticism for using drones in military offensives, the feds are dragging their feet when it comes to approving drone aircraft for commercial use. Japan has used drones to spray crops for 20 years, and Australia started using them to cover cricket matches. In the U.K., drones are used to check the undersides of oil platforms for repair, and Domino's got away with doing a stunt drone pizza drop. Still, the Federal Aviation Administration has outright banned commercial drone use, but the reasons and regulations are fuzzy. In fact, this month, a federal judge dismissed the only fine issued to a commercial drone operation, claiming the agency can't enforce regulations that don't exist.
