“The absence of evidence not being evidence of absence (without other evidence demonstrating why evidence ought to be expected in this circumstance) is self-evidently true logical axiom.”
I’m confused you had it right the first time with your excellent airplane example.
Though you dont need to be that complicated.
The classic example is if I say there is an elephant in the room (a literal elephant). You can quickly look around not see it and prove me wrong. Thus absence of evidence is in fact evidence of absence. However if say there is a flea in the room. Your not seeing it is not evidence of is absence.
Arguably the elephant being a large visible animal that cant hide in this small room is “other evidence demonstrating why evidence ought to be expected in this circumstance” but tht is often the case.
