Fort Huachuca is a US Army base in Sierra Vista, about 25 mile south of us. The base regularly flies a tethered aerostat (blimp) that contains a radar system and is used to look at the US-Mexican border airspace. I first saw it a couple of years ago from our RV site in Benson. We go to Sierra Vista somewhat regularly and see it flying every so often. I’ve tried to get pictures of it several times and most of the time the photos haven’t come out very well which is usually because the lighting has been bad. This time I got a reasonably good photo of it.
A half hour later a thunderstorm suddenly came off the mountains that form a backdrop southwest of Sierra Vista and they quickly reeled it down.
