Imagine how expensive it was to shoot down this balloon. We sent an expensive F22 which burned a ton of fuel and then shot a very expensive missile at the balloon AND several ships had to clean up several miles of debris?? Send China the check.

I ignore the majority of it myself. Maybe I'm a pessimist but there is little I can do to make an impact on geopolitics. I want to spend my energy on the things I can control and little energy on anything else. I'm much happier being completely unaware of whatever may be happening with the world.
> Maybe I'm a pessimist but there is little I can do to make an impact on geopolitics. I think quite the opposite — Geopolitics is impacted all the time by your actions. What you buy, what you say on forums like HN (where potentially tens of thousands read your comment), how you educate your kids, how many kids you have, how you influence co-workers. The reality, is the world is smaller than you think. What’s the phr…

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.
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.

Judging from the videos that pan from the moon to the balloon: the balloon was about 3x smaller in the sky than the moon. Knowing the altitude of the balloon was 68,000 feet, we can fudge the distance from the observer to the balloon as 100,000 feet. Knowing the distance to the moon and the radius of the moon we can use like triangles to estimate that the balloon was ~285 feet across, +/- 20% for estimates. Edit: upd…
This is a clever method and I appreciate that you posted the Wolfram alpha link - always happy when people show their work and I did not realize that you could do things like include (diameter of moon) as variables with it. This is a nit, but if you're busting out an AI enhanced calculator there is no need to make a 40% rounding of 70K to 100k. I got ~200 ft across.
In previous times, the US would ignore these balloons and quietly take them down. Instead they made a big deal out of it and milked it. Brilliant and opposite of what china expected
I have been in "no politics, no news" mode for over a month. I try to do this about once a year. I have yet to tell my wife I do it, but when I am on this limited media consumption she always comments how pleasant I am to be around. I think it is a good thing for all of us to do once in a while, until 80 years ago most news was at best three or four days old, go back 120 years and you're getting only last weeks top t…
Sputnik 2.0 It's a serious warning that the U.S. is dangerously behind China when it comes to balloon technology. Note also, balloons are one way of colonizing Venus (floating high in the atmosphere without having to approach the dangerously hot surface). Clearly we need a Venus Balloon Program to show who's the technological leader on this planet, just like with the Apollo Mission. Mars is for wimps, real explorers…

It looks like the large size is mostly just solar panels (I'm assuming that's what they were; they could have been 'sails' to help steer it) and their scaffolding. From some of the available photos there's two wings, each with eight panels. There's a tradeoff between the weight of the solar panels vs simply using batteries (though batteries don't like the cold, and solar panels do), so I think maybe they were hoping…
When an aircraft doesnt have a transponder, doesnt respond to radio calls, no flight plan on file, and seems to be adrift, it is a hazard to navigation irrespective of altitide. Such things get intercepted and, if in any way dangerous, are shot down. Post-9/11, there are even protocols for shooting down unresponsive airliners.
This is technically the first combat kill by the F-22.
