USAF Might Be Shooting Down Hobbyist Balloons 136

New submitter kalieaire writes: Steve Trimble of Aviation week reports that a Hobby Club's missing ballon might have been inadvertently targeted as a malicious UFO and subsequently shot down. When Scientific Balloon Solutions (SBS) company founder, Ron Meadows, reached out to Gov't resources at the FBI and DoD, they were brushed off. "I'm guessing probably they were pico balloons," said Tom Medlin, a retired FedEx engineer and co-host of the Amateur Radio Roundtable show. Merlin has three pico balloons in flight in the Northern and Southern hemispheres. According to Trimble, the description of all three UFOs shot down during 2/10-12 match the description of pico balloon models which can be purchased for $12-180 each, depending on the type. "Launching high-altitude, circumnavigational pico balloons has emerged only within the past decade," writes Trimble. He continues: Meadows and his son Lee discovered it was possible to calculate the amount of helium gas necessary to make a common latex balloon neutrally buoyant at altitudes above 43,000 ft. The balloons carry an 11-gram tracker on a tether, along with HF and VHF/UHF antennas to update their positions to ham radio receivers around the world. At any given moment, several dozen such balloons are aloft, with some circling the globe several times before they malfunction or fail for other reasons. The launch teams seldom recover their balloons.

The balloons can come in several forms. Some enthusiasts still use common, Mylar party balloons, with a set of published calculations to determine the amount of gas to inject. But the round-shaped Mylar balloons often are unable to ascend higher than 20,000-30,000 ft., so some pico balloonists have upgraded to different materials. [...] In fact, the pico balloons weigh less than 6 lb. and therefore are exempt from most FAA airspace restrictions, Meadows and Medlin said. Three countries -- North Korea, Yemen and the UK -- restrict transmissions from balloons in their airspace, so the community has integrated geofencing software into the tracking devices. The balloons still overfly the countries, but do not transmit their positions over their airspace.
On Feb. 15, NSC spokesman John Kirby told reporters all three objects "could just be balloons tied to some commercial or benign purpose," but he did not mention the possibility of pico balloons.

    Sending up balloons to float in commercial airspace sounds like a really really dumb thing to do. While they wouldn't bring down a plane they'd could easily disable an engine if injested by one.

      While they wouldn't bring down a plane they'd could easily disable an engine if injested by one.

      That seems unlikely. The mylar balloon isn't going to trouble a gas turbine, even if it made it into the core (unlikely). The tracker has a weight of 11g and is going to be mostly plastic, so while it could put a ding in a blade it's also not going to trouble the engine. The blades are actually damaged quite often by the ingestion of small items on the ground and it's a regular maintenance operation to have someone inspect each blade and file out any small dents or pits to stop crack formation/growth.

      I guess if the balloon got into the air intake of a piston engine and blocked it up that could certainly be a problem, but it would be an extremely unlikely sequence of events for that to happen.

      BTW, I imagine one of the reasons they have this exemption for balloons like this is because of weather balloons. I believe something on the order of 2000 of these get released around the world each day. They are vital to our modern weather modelling infrastructure.

      • Sounds like you're talking about the Chicago Convention, which allows light balloons at high altitudes, exclusively for weather, to go unmolested. This isn't an FAA exemption, it's a UN treaty.

        An FAA exemption would only apply to the US anyway, not international airspace.

      • While they wouldn't bring down a plane they'd could easily disable an engine if injested by one.

        That seems unlikely.

        pico balloons are up to 8 feet wide [theguardian.com]. I'm no aircraft expert, but I wouldn't want that wrapped around a propeller or sucked into a jet engine.

      The balloons in question are tiny and carry payloads measured in the tens of grams. They are under an FAA exception due to their weight (under 6lbs does not require a transponder), and that FAA exception was created after the _FAA_ studied the dangers thereof. That's the point of the exception. There are probably hundreds, not dozens, of these things floating about right now - they _explicitly_ were not tracked or cared about until this most recent international flap occurred.
      • Sounds like a great loophole lol e for a spot program. China just needs to miniaturize to get those signals intelligence payloads under 6lbs, and they are good to go.

          You're talking about miniaturizing something the size of three school busses down to six pounds.

          The Chinese "spy balloon" was technically a dirigible -- an airship with steering and propulsion. While that propulsion was limited, it enabled to the balloon, once in the general area, to steer itself over a target and maintain position long enough to collect data on activities at the site. It's going to be awfully hard to implement that kind of capability in a form factor that looks like an innocuous weather balloon. Don't you think the Chinese *would* have miniaturized their robot airship if that was feasible?

            There's more to it than just safety. If an engine blade is damaged it needs to be replaced; even if the aircraft lands perfectly safely. That means aircraft downtime, engine downtime, replacement parts and tools, and labor. And there's always the possibility that a diversion airport doesn't have a maintained depot; which means all of the above needs to be flown in. and ALL of that costs money. Even if that's inadvertent, there is a civil tort there. The people littering and damaging others' property need to be identifiable and held liable. Or just not allowed to litter in the first place.

            Look at it from an automotive PoV. Running over a nail in the road won't crash my car. It might not even ruin the tire, depending on where exactly it got stuck. But even just a tire patch costs me money to have patched. And if some fuckwit was known (or has admitted) to going around town planting nails in the roadways for people to run over, things aren't going to work out well for him.

          Thing is, most of this damage comes from ingesting things like rubber from tyres of a plane that landed before yours, or parts of tarmac that got dislodged by a landing and braking. Sometimes it's also small parts of brake pads. All of these are way worse than a balloon of this kind, and engines a

      "One part of the amateur radio hobby is launching high altitude balloons with various radio and other payloads. Larger amateur radio balloons launched in the USA require FAA clearance, need a radar reflector attached, and usually continually transmit APRS telemetry before naturally popping and falling back to earth after a few hours, just like a weather balloon.

      However there is also the simpler 'pico' ballooning hobby, which involves the use of mylar helium party balloons to launch small solar powered payloads that are only a few grams in weight. They typically transmit low power WSPR at HF frequencies and can only transmit whenever there is sufficient solar power available. Amateur radio or SDR hobbyist stations around the world can pick up these transmissions, and report them on amateur.sondehub.org and/or wsprnet.org. Well built balloons can totally circumnavigate the globe several times over several months before degrading.

      While termed 'pico', the party balloons used can still be roughly a meter in diameter on the ground, with some latex balloons potentially expanding further at high altitudes due to the low atmospheric pressure. These balloons can be legally launched from almost anywhere in the world. In particular in the USA there is no FAA clearance required to launch them due to their payload being much less than the limit of 4 lbs (1.8kg). "

      I doubt the equivalence of large party balloons would do more damage then e.g. any typical large bird.

    It is an over-reaction to having done nothing to stop the one real spy balloon before it finished its mission by going all the way across the USA. So after being heavily criticized for inaction, they turned up the sensitivity of the radars (or threshold of what to worry about) and spend $400,000 a pop missiles to take down harmless stuff.
