I agree completely. A Few ruin it for all of us.And those rogue pilots wonder why the FAA is coming down on all of us with massive restrictions and regulations. I hope that each pilot that was caught flying illegally gets a hefty fine and possible confiscation of their drones. Further proof that you can't fix stupid.
I understand your point. I have numerous of cuts on my hands too, but it's difficult for a drone to cut balloon's fabric.You are correct that there were no incidents derived from the illegal flights. However, I beg to differ with you in respect to the possibility of a drone creating a hole or tear in the balloon fabric. The spinning blades are like shredders when spinning at high RPM rates as they do during flight. I myself have had minor cuts on my fingers from even the smallest toy quadcopters that I own. I would shudder to think of such an incident perpetrated from a drone the size of the Spark. And I would expect that some of the drones that were in flight that day were much larger like a Mavic or even an Inspire. I have seen videos of these aircraft coming in contact with tree limbs and the way that they can shred those small branches and limbs is a clear indicator of the destructive power of those blades. A drone at any speed can create havoc when coming in contact with any soft tissue albeit fingers or ripstop nylon or even dacron as these balloons are built from. This I am fairly sure of. This of course is only my unsubstantiated opinion as there are no documented cases as such with hot air balloons and I certainly hope that there are never any to report. Your opinion is duly noted and respected as given.
