I don't want to be mean or anything, but how many miles apart are these planes?
You can't call it a 'close call' unless you actually zoom in a lot moar. Look at linear distance as well as altitude. For next time.
What is your rationale for assuming that aircraft not displaying ADSB callsigns are drones? Have you tried looking up the ICAO numbers, or has ADSBexchange disabled that feature? Sometimes just a plain web search will find an ICAO number.
I searched 2 ICAO numbers and failed to ID them. However AE67A7 has appeared before, even godlikeproductions faggots noticed it "2 X USAF UNIDENTIFIED AIRCRAFT ICAO CODES - AE680C & AE67A7 CONTINUE HDG SE LOCATIONS AT 20:30"
No idea what date that post was made, it's a closed forum.
Try zooming in on the no-callsign aircraft and turn on tails so you can see their trajectory and notice how long they have been in the air and at what altitude and speed.
Anyway, it's unplanefaglike to "assume" anything. We thrive on data.

That's what The Plan wants you to think right now, isn't it.
