In Aviation E Brief today it is reported that The FAA have received more than 325,000 UAV registrations making more drones than piloted aircraft at 320,000 in the USA!
2 points from this.
1) Time for a rename of FAA to FDA Federal Drone Agency? or I would LOVE to hear YOUR suggestions!!
2) Possibly the ATC and control towers etc should concentrate on looking after the UAV's nicely and keep them piloted aircraft out of the way now we have Superior numbers!.
Just kidding, good luck USA.
