Years ago I had Night Watch circling my area for hours.
Every time it was due to pass over I went out to see if I could see it.
No joy.
Very far up.
It was freaky though.
I did get to view an oddity in 2023.
A K35 was refueling overhead at 5,000 feet!
Over an HCA (populated area).
Saw it on ADS and went out to watch.
It was like a “performance”.
Very cool.
And, don’t ask me why this happened.
I live near Saginaw, so not a big center of interest.
