Based at KRYY (McCollum Cobb County GA) there are a number of FWK*** flights. That is FlightWorks a private charter company. I know the owner so that is how I know who they are. FWK920 This is one example.
I wonder if there is a way to show that FlightWorks is the operator instead of “unknown owner”. They hangar and charter out with their planes.
Here is their website FlightWorks
