Probably old news to many, but I find this quite interesting. Strange trumpet-like noises have been reported bellowing from skies all over the world. Have so far been unable to discover any explanation, although being the practical type I've no doubt there is one, even if it's just one huge hoax. This one in particular is very eerie and I would have loved to have been there when this happened. Listening to this one again, it sounds like some kind of sound effect dubbed over the clip, and the people are reacting not to the noise, but the approaching storm.
