Well it was bound to happen. I wonder when all of this will get out of control and a passenger hot air balloon gets shot down?

Well when a balloon gets sent up for amateur use or weather or personal use it's probably a good idea to register it with the proper authorities with full disclosure of purpose and intention. May keep it out of Harm's Way.

Hot air balloons operate up to about 3,000 feet. Identification would be easy.

An amateur radio balloon is inherently inexpensive and is likely to be 'disposable', since it it is likely to come down into the ocean or a remote area.

On a few projects in the wilds of Nevada we would fly large balloons (12 foot dia.) trailing an equipment package and a parachute on 30 foot-plus tethers. These things could reach a altitude of 30,000 feet before exploding----why they all had parachutes !!

Every day I would file a "NTA" --Notice to Airmen -of what we were up to that morning, with the FAA. The only time anything 'went wrong' was when I used too much aluminium foil protecting the equipment.... for it lit up radars really well like it was the Hindenburg--- prompting a call--

"What the (-----) are you guys flying out there ??!!"

I smell a TIS-B requirement in NPRM from FAA soon for balloon flights below 4 lbs. APRS / transmitted location from other than ADSB/TIS-B will not be sufficient, particularly if these are sub FL400 near high altitude airways.

Hate to see it, but that's the world we live in.

Yup.... These balloons are very popular STEM projects now...

This subject is also going on over at the mid-atlantic mil-air forum...

My 2 cents was

On a slightly, ( but just slightly) more serious note, there are a LOT of weather balloons sent up, even hobby APRS transmitters can be modified so that amateurs can get GPS altitude readings when over 80,000 feet. (look at Byonics Byonics - GPSs for GPS5, and GPS5HA)

It seems like a boy scout / science project level exercise to launch model rockets and weather balloons.

You searched for altitude | Tracksoar

(check out the Texas teams flight (107,000 ft)

The most likely two things to happen that will make lots of sense are.

1. Make sure everyone understands the rules about sending up balloons.
2. Put optical trackers / medium power lasers on pods (external fuel tank size ) that can take out the relatively cheap balloons without using very expensive missiles.

On a less serious note... Something I came across a while ago, and I've been trying to find the popular science / popular mechanics advertisements for the black cylindrical balloons. but I couldn't find the advertisements.


Thanks

For our anniversary last December I bought my wife a pendant that was claimed to have flown to 102,806 feet above the Sierra Nevada mountains. It was added payload to help pay for a cosmic ray monitoring helium balloons. They say in the documentation that the balloon "exploded" and the payload parachuted back to earth. I didn't see any scorch marks from an air-to-air missile on it.
I thought what the heck seemed like a nice (relatively cheap) gift, why not.

That's awesome, what a great idea !!!

It had occurred to me to collect some of those thin laundry bags. I have an old aluminum lawn chair. That was a thing once..

".......Don't tempt me! I need some comic relief right now and that could be funny........"

Here's one for you :)
I can look at your balloon and smile--- for time has soften an experience ;) .

_____________________________________________________________________________________________________

I used to be a Balloon Mistress (if that is a good term) who flew these big 12 foot-plus monster balloons laden with our various equipment packages. One thing that never seems to gets mentioned about balloons this size is just what they are capable of lifting.

Granted, if you are holding on to one it will not carry you off like Dorothy to the Land of Oz, but they will lift you off the ground if you want to try to 'moon walk"- which is sort of a bounce-about. We were quite cautious about doing this, especially in the deserts where a 'moon walk' could land you in a patch of cholla cactus (oh ! the painful voice of experience.)

But a particular episode that stands out in the annals of (foolish) playing around was when one of guys -- we'll call him Bonzo for lack of a better name, (and to protect his reputation for he is quite a highly respected scientist today) -- decided to fill enuff balloons to achieve a neutral buoyancy -- this, to allow him to hover for several feet above the ground for several seconds with each jump. He tied the tethers to his belt....

I think you are seeing where this is going :p .........
(This, BTW, was your tax dollars hard at work.)

Our balloon launch site was right across an arroyo from a pair of mainline Union Pacific railroad tracks,

It was a quiet period when the rest of our little team were sitting out the sweltering heat in the shade of an equipment trailer; sitting idly watching whatever the hell "Bonzo" was up too..... for with balloons attached, he was bouncing about the site, doing leaps that took him over fuel drums and other objects...


Then a sudden gust of wind------

"Bonzo" was lifted several feet off the ground and spirited rapidly towards the ditch.

Bad Timing !

________________________________________________________________________________

Rapidly approaching on the railroad tracks was a UP freight train.
"Bonzo," in one magnificent arch, bounded into the arroyo, was caught by the next gust and carried half stumbling, half flying, towards the on-coming train.

Bingo!, right into the centre of the tracks !

We idle onlookers were not idle now ! Running and shouting we watched helplessly as "Bonzo" stumbled and staggered on the tracks. The train engineer was screaming his air horn.... we expecting at any moment to see "Bonzo" turned into raspsberry jam before our very eyes-

Then, mercifully another gust of wind carried him safely off the tracks.

________________________________________________________________

Thus officially, and forever, end'd our lab's the Moon Walking Program
