I live near Mt. Holly, which is near gastonia for those that aren't familiar with the area. I don't recall hearing those sounds last weekend however I have heard similar sounds in the area before. It's hard to say if it would be anything to it however with all the large truck traffic on the interstate and the air traffic into and out of Charlotte.

Although last Saturday night I saw the most bizarre meteor in the sky as I was passing the airport on 485 heading home from work. It was bright green and looked like it was traveling straight down, as opposed to across the sky, and seemed quite close to where I was.

Yea I thought I heard something several months back but there was a plane passing by so I figured it was some weird echo off that. I clearly heard the plane but there was another sound in the background that lasted longer than the sound of the plane but faded shortly after it went by. Also remember it was only a few years ago when there was the earthquake up near Goldsboro.

My sister lives in Colorado Springs and I'm going out for her wedding in may. You better believe I'm going to pay attention and be ready to record.

Any idea when that video was made? I would be curious as to weather she heard anything at the time this was taken. She spends a lot of time hiking in the mountains so I should ask if she's heard anything like this before.

So yea, she's never heard anything like that. Oh well.

If that was Colorado springs the answer may be alot more simple than many would expect.
Fort Carson is in that area, and they do live fire exercises, and back in the mountains there are several shooting ranges, almost kind of sounds like something that you would hear from an army base doing live fire exercises. Use to hear them out on the plains east of Colorado Springs. Tanks, Morters, and the occasional black powder rifle.
