My speaking up came about because I saw a pilot at our field who had never been seen with a helicopter before. He felt is was safe to hover 5 feet from himself, there were others around within 30 feet.

I agree, you wanna fly alone do whatever.

One of my concerns comes from the fact I was the first person allowed to fly helicopters at our field.....3 years ago. Time has progressed, and now we have one fairly good 3D pilot, 4 learning (all over 60), and finally the guys have accepted them and are interested. But, if this dude were to have hurt himself or anyone else, it would have been the helicopters fault, not his, and possibly heli's could be banned from the field. I don't want to see that happen.

Again, though I have seen tail rotors fail and just miss people, I have seen blades go, dumb thumbs, etc.

Oh well, I am just becoming an old Paramedic with too much life experience and paranoia. Murphys law is functional.
