At 9:02pm CST my wife and I heard a loud rumbling sound. I walked out of my front door as we heard the sound emanating from the North. At 9:07 we witnessed several helicopters flying toward the region. I called my sister, who was also in the area, and she confirmed with several others what we had witnessed. We live right across the lake from a Fort Hood bombing range, and we hear all sorts of ordinance going off very often. We have never heard anything like this.

The sound was loud, booming, and emanated from the skies as if it were raining pure thunder for a solid thirty seconds, then stopped suddenly.

I am at a loss for what it could be. When I think it could be Ft. Hood ordinance, my mind fills with doubt. Aside from an earthquake, which I have never experienced and there was no ground shaking, there is nothing else I can conceive it could be.

Any thoughts, ATS? This is my first official post, by the way as I am usually just a lurker.

ETA a more precise location: Morgan's Point Resort, TX

Another addition: Some people are suggestion Ft. Hood military exercises. I haven't heard anything like it, and would like to say I'm well versed in the different sounds after being here for so long and given my familiarity with said events, however I cannot dismiss it as a plausible explanation. Thanks for the input

I'am in Groton,CT, i just heard a loud boom about 20 minutes ago. Anyone else hear it?

The windows rattled a little.

I'm in the Dallas area, Grapevine to be specific, and I haven't heard anything at all.

I've been sitting in my room writing and listening to Noam Chomsky lectures which were turned up somewhat loud, so being distracted and having my computer speakers blasting words of wisdom from Noam may have drowned out such noise. But if it was as loud as you say and in this direction, I'd think I would have heard it.

I'm not saying I don't believe you, mostly just disappointed I did not hear it myself!

I am constantly hearing planes taking off and landing at Dallas-Fort Worth airport also, so that probably hurts the chances of me hearing something. Definitely keep us updated if you hear any other noises or find out what it was, I am very interested.

Is it possible that Ft. Hood is ramping up its bombing training, and rained holy hell on the landscape for a while? I've been to Ft. Hood several times, but since I never lived in the area, I cannot say for sure, it's just a guess.

I did live next to Ft. Hunter Liggett in central Cali for about 10 years, and when they started with their tanks on the firing range, it was intense.....One long, continuous "thwap thwap thwap", and then "boom boom boom", very crazy and noisy.

Could it be SpaceX in McGregor, outside Waco Texas, testing engines...they make space shuttle engines. A few years ago I heard a loud rumbling one evening. The windows were rattling...just an ongoing rumbling very loud. I thought the world was ending...that some asteroid was coming in from outer space. It was overcast with clouds so we could not see the sky. I did think something was coming in as the rumbling went on and on. The neighbors in the apartment complex joined me outside, all of us scared. I phoned my sister in a town close to mine crying asking if she knew what was going on. She said there was no noise where she was. Needless to say it was scary. The next day we all heard that SpaceX had been testing some big engine and they failed to let the citizens know. It was their first test. A lot of us did not know this company even had opened this engine building complex.

But I would think I would have heard it as I am closer than you??? Guess it wasn't SpaceX.

I'min Crowley Texas, which is on the southern border of Fort Worth, I was outside 20 minutes ago and heard nothing. It's nice out, so we had the door open most of the evening. Still, nothing.
The only time I ever heard something was when the space shuttle went down. I was up early and heard what sounded like a garbage truck running into a wall at 100mph. If I would have went to the front yard I would have seen the shuttle break apart...
I will keep an ear out.

im in alabama we where having some really bad thunderstorms around that time had some heavy thunder i spend alot of time in my out back and the thing felt like it was gonna rattle apart all of our weather comes from texas we usually get it within the next two days so maybe u got under a long line of dry thunderstorms lol u never know with 2012 weather maybe there testing something new out there something that maybe could take out a nuclear site without spewing radiation in the air

Howdy, as an Austinite who lives at Lake Travis,
I have heard and posted about the rumble before.
It's low low frequency.I'll be listening. Last time I posted about it,
Was in March maybe? And it happened a few nights in a row
at about 10pm. It seemed to come from the sky to the north
of our home. Anyway, thanks for this thread and I'll be on the
lookout er.. Ear out?
