BOOM! Mystery blasts rattling the globe

Was it a supersonic aircraft? A meteor? A ground explosion? The end of the world as we know it? Those are the questions experts and non-experts around the world are asking themselves in recent weeks as curiously loud mystery BOOMS have not only been hear around the world, but felt – shaking buildings and rattling nerves from Alabama to Michigan, Idaho to California, Russia to Denmark. The Alabama boom last Tuesday at 1:39 CST was heard and felt through 11 counties, but an earthquake event has been ruled out.
