Well I know I'll never convince you it's a good idea so I'll simply attempt to reinforce my perspective. I will also not attempt to convince you of the possibility of dire effects of a lithium battery dissolving in a geothermal pool. You obviously know more about the science of geothermal water chemistry than me. Or the experts.
2 personal examples of why I am all in favor of a total ban in National Parks: The first was 3 years ago in Grand Teton NP. My wife and I were out doing some sunset photography and just enjoying the evening. A truck pulls up and parks about 100 yds away. I never even paid any attention. A few minutes later, we had a drone buzzing around. An angry mosquito sound ruining the solitude. I'm a pilot, I've been flying model aircraft since I was 25 (I'm 62 now), but I told my wife right then and there "These are going to be outlawed in National Parks, and well they should be." The next occurrence was in Zion NP in Southern UT. We had hiked into Emerald pools, just enjoyed the sound of the waterfall and birds. 30 minutes later, some idiot comes in with a drone in a backpack and starts flying the waterfall shooting from the top to the bottom. It was ridiculously annoying and I repeated my hope they would be banned. Hallelujah, shortly after that, they were! There is not one single aspect of the NP ban that I don't agree with, and I spend approximately 6 weeks of every year in our National Parks. I would LOVE to shoot aerials of what I see, but I would NEVER CONSIDER DOING IT. Even if it was still legal.
Here in my state of NC we have the Great Smoky Mountains: UAVs BANNED. All NC State Parks: BANNED. Outer Banks National Seashore: BANNED. Many city parks: BANNED. Proposals for flights over private property without permission: BANNED. Permission required to take off or land from just about anywhere, unless it is your own land.
Add the obvious legetimate NFZs for airports, military installations, MOAs TFRs, sport stadiums, wilderness areas...
If this trend toward denying public airspace continues, just where do you propose people are going to enjoy this as a hobby or pursue a growing industry? From their own backyards, assuming they are fortunate enough to have one which is flyable and not in a NFZ?
Forget the hobby for a second. I've talked to NPS employees who say the NPS will not even allow employees to use them for research or search and rescue.
Or would you prefer that only "authorized government entities" be allowed to use them within the confines of the parks? Because, make no mistake, benefits of drones within the vast park boundaries is recognized, undeniable, and inevitable.
You should be aware that in my state alone this includes hundreds of thousands of acres of land (perhaps millions as I haven't done the math) where NOBODY is even around to be disturbed. In fact, my wife and I travel the State Parks, National Park, and National Seashore extensively and most of the time there is no one, I mean NO ONE within miles of where we are. It therefore makes no sense to ban them from vast areas where no one or someone would even occasionally be exposed.
Since you're on this forum, you are no doubt aware of where this technology is going, how small it is, and how it is bound to get smaller and quieter with each passing month. But, never mind that, once these rules are permanently in place, as you hope they will be, they are never lifted no matter how friendly the technology becomes, and exceptions are not made without an act of Congress... especially once public opinion has been soured by fear mongering reports of how large, intrusive and potentially damaging to society (or better yet, the environment) they are, even as every day they move further and further from that narrative.
Just today, I was in a NC State Park, immediately adjacent to the Blue Ridge Parkway, and the single engine manned aircraft, circling overhead and the Harleys blaring by below us were many decibels above what my Mavic would've put out, so forgive me if I am somewhat annoyed by those who use this, and the fact that my little 20oz drone might clog up a 2 acre hot spring, as ammunition to incite negative public opinion.
And all because SOMEONE, or some creature. might be bothered by an occasional buzz which isn't even close to the blaring Harleys cruising along the Parkway? This would not even be an issue if properly administered.
So when you use the excuse that you can't be bothered by a little noise, who is being selfish here?
I am not advocating for an anything goes policy here, as I like my peace and quiet as much as anyone, but what we have now, and what you advocate for is overkill IMO.
You are correct, I'll probably never change you opinion either, but I just hope clearer minds prevail and recognize the benefits of embracing this technology, everywhere it is appropriate, regardless of what agency boundary it happens to be within.
