UFO's Causing 'Trumpets of the Apocalypse'?

Here is a video you should watch if you are unfamiliar with the strange sounds being recorded from all over the world. 

I have not seen a good explanation for what is making these sounds.  They sound like trumpets.

What is really interesting is that they seem to be in the same pitch, playing the same notes where ever they are recorded.

The clip that I have posted is making the claim that UFO activity is reported in the area where the sounds are being heard.

Some Bible readers are wondering if this isn't the angels warming up their lips to blow the trumpets which will sound announcing the rapture of the church.

Some alien watchers are wondering if these sounds aren't announcing the soon return of alien beings from other planets....which we believe are actually demons in disguise.

Other Bible readers wonder if this is what is sounds like when the earth groans....groaning for what it will become once Christ returns.

I guess we will all have to be Bereans and see if we can make any sense, or truth, of what this phenomenon really is.
