Im sure the FAA and Homeland Security would as well. Not sure about the FBI and the NRA though.
Now that "drones" are registered as real aircraft all federal laws apply regarding shooting at them just as if you shot at a real plane.
Kinda why FT has backed away from the more extreme side of cool and crazy ideas.
Not really. There's a machine gun shoot in Arizona where people throw RC aircraft up in a valley and other people man literal machine guns of varying sizes to try to shoot them down. Everything from full auto AR15s to M2 Browning twin-mounts.
All done in total safety and legality, too. Under the right circumstances, yes, you
can take potshots at an RC aircraft with actual firearms. But it needs to be done right, at an event like the Big Sandy Shoot where all the necessary precautions are in place.
