I was just about to say that

I worked on something that literally said "to test this thing, hit it here with a screwdriver" because it was known to be a point where a soldered joint would fail

I used to bash the shit out of some stuff with a hammer to prove my diagnoses. It wasn't working anyway, so I couldn't break it more, and I was usually proved correct when I was able to replicate the failure

And now interplanetary percussive maintenance is a thing too.

U gotta account for the different air density and effects on sound due to that
