If UFOs are not balloons or “craft” but undefined “airborne trash”, what is the AARO or debunker definition of airborne trash? Put it into my hands. What exactly am I holding?

Aside from balloons, Starlink and other satellites, various stars or celestial bodies, human-controlled known craft, and known aerial phenomena like lenticular clouds or sun dogs, the modern “fall back” to the silly remark by J. Allen Hynek in his early days of Project Blue book of ‘swamp gas’ seems to be “airborne trash”.

I never see any examples of what that actually would be. It just has evolved into one of those final last ditch things like: “I cannot, ultimately, explain what this UFO was. However, since ideology or policy requires me to never leave open the possibility of even an avenue toward non-prosaic answers, we must conclude it was airborne trash.”

If UFOs are not ultimately known things but undefined “airborne trash”, what is the AARO or debunker definition of airborne trash?

Swamp gas made flesh?

I would like to see cited examples of ACTUAL airborne trash that was reported by civil aviation. Take one of those identified ‘things’ that is airborne trash out of the sky. Put it into my hands.

What exactly am I holding, if not a balloon?
