It is perfectly possible (and imho the most likely) that we have a small fraction real hostile drones and a large fraction resulting drone hysteria.
We will not prove or disprove that with these fourth-hand imprecise descriptions of observations matched to flight tracks.

Reminds me of the "Chinese balloon" scare of a few years ago. When the US Air Force was shooting amateur radiosonde balloons.

I hear you. Once during archeological fieldwork, while jumping a small ditch, inadvertently jumped right into a clump of giant Hogwood I somehow missed, luckily for me while in coverall and with workgloves on so it did not turn out dramatic....

Reminds me of an archaeological dig I was participating in, 30 yrs ago, camping in the field. Walked past the latrines one evening (trenches with planks over them), and heard a voice from the latrines exclaim in despair: "Oh damned, I dropped my torch in the shit!"

Location at time of observation.
This was a difficult object to model in our reentry model: very eccentric orbit (brief dips below 1540 km), and indications of changing attitude =- changing drag area

You would expect that from a Miss Norway rather than a Miss Chile
