The Air Traffic Control Association (ATCA) holds an annual affair. This year the FAA set up a "Drone Zone". Most of the time a Phantom 2 was flying, but they had many drones surrounding the drone cage. My interest was in the Insitu fixed wing UAS which is a competitor to a UAS we sell but you can see the P2 flying around in the cage. The young FAA pilot was telling me he loved his job.
