It could be checking out to prevailing winds Perhaps China is worried about nuclear fallout when they nukas us Or They could have hundreds of thousands of balloons ready to go, just float over this country and then whatever they’re gonna do with them they are going to do. Maybe they just need to know to prevailing wind across the country to do that.
They have satellite data, they don’t need to eyeball a balloon.
There’s a ton of data over decades showing prevailing winds.
There’s an overall structure to the winds, but flux is perpetual.
It doesn’t make sense…
