You are vastly underestimating how important size is. It’s a huge difference to track a pickup truck vs the nail that falls off of it. The military was tracking baseball sized objects in 1961, amateurs are over 50 years behind the curve on this stuff.

Wasn't the military using a huge radar to do that in 1961? Amateurs aren't even allowed to think about doing that, then or now.

That doesn't really counter what they said.
