LOTS of activity today on the Flight Apps. Down south, up north, and above "a Remote operating location".
Caught a plane on FR flying over R-4808, almost directly overhead the radar sites Gariac reported on by the back gate entrance to groom.
The flights callsign was "ID". I had to laugh.
Anyways, onto the subject:
