The FAA is still trying to figure out the best way to regulate drones to ensure safety. Last week, a committee tasked with tackling the issue met for the first time, including representatives from Amazon, Ford and NYPD. One of the items discussed was a better way to identify registered drones from the ground since any ID numbers are pretty much invisible while the UAV is airborne. This could be a workable solution for commercial drones, but since a Washington, DC court struck down the FAA's registration requirement for personal machines last month, a remote ID system isn't the answer for all of the UAVs flown in the US -- right now, at least. As Recode notes, Congress is working to restore mandatory registration which would be key to tying a drone to its owner for the purposes of any remote identification.
