There is no Bergstrom AFB, although there was until around 1990 or so. Now the runways are part of the new Austin-Bergstrum Int'l Airport. AFAIK, no military presence there at all, not even Guard or Reserve (It was a reserve only base for many years, flew fighter aircraft, but the squardon, part of the 301st TFW IIRC, was eliminated when the F-4 Phantoms went away. The other Squadron (and the Wing) converted to F-16s at Carswell AFB, (Now JRB NAS Ft. Worth).
Thanks for the update. I was listening to three tv's and trying to take note at the same time. I heard Bergstrom and I lived up in Austin years ago and assumed they were talking about the old AFB.
They forced that plane down with three Mexican Nationals and a later search turned up 108lbs. of pot.
