A federal appeals court on Friday struck down a federal rule that required owners of recreational drones and other model aircraft to register the devices with the Federal Aviation Administration. The FAA had announced the rule in 2015 in response to growing reports of drones flying near manned aircraft and airports. Drones have become increasingly popular with hobbyists and more than 550,000 unmanned aircraft were registered within the first year it was required. From a report: The court ruled that the FAA's drone registration rules, which have been in place since 2015, were in violation of a law passed by Congress in 2012. That law, the FAA Modernization and Reform Act, prohibited the FAA from passing any rules on the operation of model aircraft -- in other words, rules that restrict how non-commercial hobbyist drone operators fly. Now, if a person buys a new drone to fly for fun, they no longer have to register that aircraft with the FAA. But if flying for commercial purposes, drone buyers still need to register. The lawsuit was won by John Taylor, a model aircraft enthusiast, who brought the case against the FAA in January 2016. Since first opening the FAA's registration system in December 2015, more than 820,000 people have registered to fly drones.
