How does a surveillance balloon get the collected data back to where it is analyzed and used? I suspect the data is relayed by satellite (unless there are collection sites within the US). Which Chinese satellites are able to cover the US?

Almost certainly by satellite. To wit, every iPhone 14 now has an emergency text feature that works via satellite-- you could potentially just use one of those and send everything base64 encoded.

Im pretty impressed that it made it all the way across the continent in a couple days, i had no idea high altitude balloons could move that fast.

Winds are seriously fast at higher altitudes — check out the different wind speeds using the "height" option on this site: https://earth.nullschool.net/#current/wind/surface/level/ort...

From your point of view, I can see how China is bad and the USA is good. But ask someone whose country got invaded by the USA or whose bloody dictator got supported by the USA. Over here in Latinamerica we still remember the horrible things that the USA did. It seems to me (but I could have a false perception) that China is a horrible bully in their corner of the world (nine dash line and, of course their will to inv…

That's what they did to Tibet for example and they absolutely are an extreme ongoing threat to Taiwan

What did they do to Tibet? The CIA tried to establish an independent Tibet so the US could have bases there, and later engaged in “Free Tibet” rhetoric meaning US weapons in Tibet, and China went to great expense to build a railroad to Lhasa to keep American weapons out of Tibet.

China doesn’t want US military bases on their side of the Himalayas. It remained an autonomous region until a bunch of clowns proposed putting US military assets there.

Wouldn’t you expect video to surface of f-22s in action?

F-22s we’re designed to guide weapons to targets.

Ukraine launches a few rockets and a stealth f-22 off the coast can guide it in.

Something like this seems plausible here: https://www.bbc.com/news/world-europe-62500560

There are some alternative theories (small drones painting targets), but imo it’s just as plausible a stealth plane 50 miles away gave a missile some coordinates

The engines have a distinct sound so the video wouldn't even have to be pointed up at them.

Do you really believe the USAF and rest of the military and 3 letter agencies had not already intercepted/jammed/hacked the comms link? By letting it saunter all the way across they also probably got a lot of good info on its capabilities.

Must be nice being so privileged to talk down the very thing that maintains global trade channels (diplomacy) and keeps most of the world in check. Most of the world is backwater nations who oppress the shit out of their population making whatever faults you find in the US seem trivial. And yes the world isn’t fair and entropy exists. EU is basically a forced alliance after thousand years of constant fighting that led to the Nazis and fascists rising to power who had to be put down, then having to maintain an eastern bulwark against the Russians (paid for by USA let’s be honest). Let’s see how well it holds.

If anything I think the USA needs to double its military spending and increase the size of its navy and international dominance.

North America is safe and will continue, even if the whole world burns or even ICBMs are deployed towards the major cities.

I had seen reports that the balloon was the length of 3-4 school busses but it appears that was misreported and just repeated. The PAYLOAD was the length of 3-4 school busses. I haven’t been following this much until today/ vaguely aware as an amusing background story. But, has anyone seen high res photos of the balloon or someone doing back of the envelope math on the size of the balloon portion? I ask simply becaus…

The ballon was at 60k feet and eye witnesses said it had the same apparent size in the sky as passenger jets flying nearby at 30k feet.

if only i paid attention in trigonometry..

Technically the ballon isn't moving itself in anyway at all, it instead is depending on the wind. As the atmospheric pressure lowers the maximum speed of the wind can increase greatly. For example the speed of the jet stream commonly exceeds 275 miles per hour. It looks like the strongest jet winds were closer to canada, had the jet been in the US it could have made it across the country in a day.

There was mention by the Chinese that is had some motive power of its own, or at least strongly implied when their PR said some the thing like “limited maneuvering capability”. That seems to indicate that it had some. It would a bit surprising if a payload the size of 2-3 school buses wasn’t outfitted with a reasonable amount of controllability, at least some control surfaces even if they inexplicably excluded even m…

How would you collect it?

With our Star Trek level tractor beam. Of course, maybe we wouldn’t want to reveal that kind of capability to the world just yet.

I was thinking more James Bond. High Altitude Jet Pack.
