Just wondering - balloons aren't exactly a novel technology. And they are comparatively cheap to produce.

So if spy balloons were considered a real threat - why isn't there a more cost efficient way to take them down?

The new balloons fly extremely high, up to 80K feet, near the edge of space, where planes cannot reach. And planes that can reach, can't slow down enough to reach out and grab an object.
