Hoss,

The unsafe operation you observed wasn't caused by the type of flying machine (could as well have been any sort of flying model other than CL), but by the operator's negligent actions. And what of rules in effect at the site?...........I'm sure your site is under control of an AMA chartered club. Did anyone call him on it? AMA rules for MA that some would call 'drones' are pretty recent, but it has long been required that the pilot maintain visual contact with the aircraft.

May seem picky, but the public association of 'drones,' which can stretch to any remotely piloted aircraft, with undue hazard to their welfare and rights like privacy is misdirected similarly. As with NRA's concern, the problem isn't the gun, it's the felons and nut cases that abuse them.
