Unusual shut down if a fairly major airport for 10 days....national security? Terror threat? Or ???

This is very strange, particularly since the prohibited air space borders Mexico. I can think of two possibilities:

1. Intel was received about some sort of air threat to the El Paso/SE New Mexico area.

2. Holloman AFB is near El Paso (95 miles away). Could it be the base for some sort of upcoming military operation?

There is currently an observation balloon (belongs to CBP) hanging SW of Fort Davis.

If you’re looking for weird, White Sands missile range is near, as is the Trinity Site, Roswell and everything else that goes into such stories.

The sound I heard was extremely strange and long.

I’ve heard my share of jets and diesels and conventional and rocket artillery and this was something else.

The closet I’ve ever heard was turbine diesels for a frack job as they crank up and go for hours. This was not that.

Saw speculation about Holloman and WSMR. They have hosted Precis>on Navigation and Timing Experiments PNTAX in the past. Should have been much more warning.

Fort Bliss is AT El Paso. They have the Army's air defense training mission.
