Just in aeromodellers hand? I worked in the military UAV market for many years and you may be sure aeromodellers are not the most dangerous chaps!

I was told how a 0.8 mach target jet went up over a crowded city till engineers were able of recovering the control and make it back to the sea for a ditch. Or how they "targeted" a house on a nearby camping with our own prop driven UAV, thankfully without any victim but just the little house!

As they say, "the true is out there" but.... it is aeromodellers who needs regulations and being controlled.

Best Regards.
