First, it's not circling the airport, it's circling this: https://guardiancenters.com/ - A military/LE training center (a very cool one, too). It jumped out of that pattern once that I can see so far, creating the "Q" shape in the process. Also, it's a county airport - there's no way it would have that much traffic for a plane to be in that long a pattern. They'd just divert it to another airport if they couldn't clear it in. Also, it's doing over 200 kts.
