Have you looked at them lately? There are planes being flown virtually like they do with predator drones. Videos are on Youtube. Rig one up with a cell phone as a data link, and with enough fuel or batteries, I can see how one can be used as a weapon.
If Barbara Gray, the “Strange Lady from Framingham” was still in office. RC planes would be recalled like they were Lawn Darts.
Yeah; technology marches on, with GPS and smart phones, etc., but a balloon, helicopter, and many other items could be fitted with control apparatus and carry a payload to a target. Not many would set up a Trebuchet across from the White House today....
The point is, nutcases put bombs in their shoes, shove explosives up their asses, etc., and you can't "REGULATE" behavior or toys simply because nutcases can buy them. It's stupid to give up ALL your freedom, and strip-search grandma while letting towelheads go through because of "profiling" lawsuits....
Get a grip, America.
