President Trump signed a sweeping defense policy bill into law on Tuesday that will allow the government to require recreational drone users to register their model aircraft. This comes after a federal court ruled in May that Americans no longer have to register non-commercial drones with the Federal Aviation Administration (FAA) "because Congress had said in a previous law that the FAA can't regulate model aircraft," reports The Hill. From the report: In December 2015, the FAA issued an interim rule requiring drone hobbyists to register their recreational aircraft with the agency. The rule -- which had not been formally finalized -- requires model aircraft owners to provide their name, email address and physical address; pay a $5 registration fee; and display a unique drone ID number at all times. Those who fail to comply could face civil and criminal penalties. While Congress directed the FAA to safely integrate drones into the national airspace in a 2012 aviation law, lawmakers also included a special exemption to prevent model aircraft from being regulated. A D.C.-based appeals court cited the 2012 law in its ruling striking down the FAA drone registry, arguing that recreational drones count as model aircraft and that the registry counts as a rule or regulation.
