When the Confederate Air Force left Harlingen it dispersed into many small wings and flights scattered about the country and seems to have lost its cohesion, also many of their aircraft migrated to fly under other banners. I fear the massive displays that Harlingen used to host are long gone.
When I worked there in 1977 it claimed to be in the top ten Air Forces in the world by aircraft numbers. A nice piece of Texan whimsy but they took it all pretty seriously.
