sounds in the sky

Hi Everyone,

I've been reading about this for a few years now.  Surely all of the videos involved can not be hoaxes, and the various explanations involving train tracks, factories, plate tectonics, don't seem to hold much water as all of those things were around before 2008.

What explanation do you all think is most probable?

I keep thinking it might be meteorological since it almost always is cloudy on the videos, and maybe that it is something involving one layer of air moving over another.  With differing density, temperature and static pressure, maybe there would be an audible sound - but surely it wouldn't be as loud as what seems to be heard on some of the videos or resemble repeated blows through an Alpine horn.  The videos include a variety of sound, so maybe some are other things, some are turbines being tested in the distance, et c.

There is a lot of professional and institutional microphoning going on in the world, and an audio recording from one of these sources would eliminate the hoax hypothesis.
