I think as in most cases of things like this there is a natural, rational explanation that makes more sense than fireworks that happen every year without incident. I also think we'll never know what it is. Probably because they're not looking for it.
I just like mysteries.
don't know if anyone mentioned this, but on my local news it said a bunch of dead birds were reported in Tennessee today that all had something blue in their beaks, and Italy had a bunch of dead Doves falling from the sky today....
THIS is Bigger than we know....imo.
