I used to work for fellow who was an Air Force Colonel in the Stragic Air Command, he saw “anomalous phenomena” on a regular basis, about twice a year. May not be daily, but doesn’t mean it wasn’t “regular”.
I used to work with a guy who had worked in NORAD. I asked him if they routine saw “Fast walkers” that come in from high altitudes (and/or space), and do things that as far as modern physics go, are impossible. He said yes. Happens all the time, and NORAD can, and does track them.
