This week's Question: Last week, the U.S. Transportation Department and Federal Aviation Administration announced that drone hobbyists will have to register their aircraft or face unspecified penalties. The move is an attempt to prevent the unmanned aircraft from compromising air safety, as the number of complaints about errant flyers has grown in recent months. Challenges remain, however, including which drones will require registration, how users will register the devices, and whether the policy will apply to devices that have already been sold or have been 3D-printed. What do you think? Do the benefits of drone registration outweigh the drawbacks?
