Look Out, America: China Can Un-Stealth U.S. Fighter Jets

5. Sort of like quantum mechanics.

Until you observe it, a particles position and momentum are not known precisely. When you make one precise, the other gets fuzzy.

So here, the position and momentum of the jet are fuzzy, but by watching it over time you can narrow it down enough that a big bomb will force it to be someplace specific and blow it up.

Well, not really, but I'm still on my first cup.

The long wave radars, like radio telescopes, need lots of aperture to provide precision, but with a big enough bomb and terminal guidance you can make it precise enough ...

This suggests that the presence of the aircraft is lots easier to detect than exactly where or what it is, sort of an out of focus image. Not invisible at all.
