The scary thing is that any idiot with the money to get one can endanger themselves and others, they are remarkably easy to fly. I'm just waiting for the first serious midair with a GA aircraft, a balloon or a glider.

That's a valid concern, but to put the risk in perspective, they weigh 3-5 pounds. Given their long-armed-structure, shape and size, a mid-air would probably be a glancing blow. A serious accident is certainly possible.

I think the people flying these are birds-of-a-feather with glider pilots and I'd hope that we stay on friendly terms and not be antagonistic when and if our paths cross.
