tally up a count of the unique flights
Most if not all of these are regional airports e.g. Dallas-Addison primarily is corporate jets, helocopters, etc… not "big" ailine planes. Galveston to Wichita could be a refueling stop. Both TX planes are following 75 north. (going to Canada?) The one doing loops over the red river maybe looking for something. That's a park and boating area between the TC and OK border. Not sure where they would land up there.
