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.
The day after Alabamans were shaken by that incident, something similar occurred in Idaho. No explanation has been forthcoming from law enforcement officials there.
Then, last Saturday, much the same thing was reported in Michigan, according to various local newscast. Still no explanation.
Clearly, it is Robur the Conqueror in his Clipper in the Clouds:
Never had the sky been so much looked at since the appearance of man on the terrestrial globe. The night before an aerial trumpet had blared its brazen notes through space immediately over that part of Canada between Lake Ontario and Lake Erie. Some people had heard those notes as “Yankee Doodle,” others had heard them as “Rule Britannia,” and hence the quarrel between the Anglo-Saxons, which ended with the breakfast on Goat Island. Perhaps it was neither one nor the other of these patriotic tunes, but what was undoubted by all was that these extraordinary sounds had seemed to descend from the sky to the earth.
What could it be? Was it some exuberant aeronaut rejoicing on that sonorous instrument of which the Renommée makes such obstreperous use?
No! There was no balloon and there were no aeronauts. Some strange phenomenon had occurred in the higher zones of the atmosphere, a phenomenon of which neither the nature nor the cause could be explained. Today it appeared over America; forty-eight hours afterwards it was over Europe; a week later it was in Asia over the Celestial Empire.
Hence in every country of the world—empire, kingdom, or republic—there was anxiety which it was important to allay. If you hear in your house strange and inexplicable noises, do you not at once endeavor to discover the cause? And if your search is in vain, do you not leave your house and take up your quarters in another? But in this case the house was the terrestrial globe! There are no means of leaving that house for the moon or Mars, or Venus, or Jupiter, or any other planet of the solar system. And so of necessity we have to find out what it is that takes place, not in the infinite void, but within the atmospherical zones. In fact, if there is no air there is no noise, and as there was a noise—that famous trumpet, to wit—the phenomenon must occur in the air, the density of which invariably diminishes, and which does not extend for more than six miles round our spheroid.
